Infância em Berlim – uma autobiografia anônima de Walter Benjamin
Authors: Otte Georg
Published: July 2015

Infância em Berlim é o mapeamento “mágico” dos primeiros anos de vida de um autor cuja autobiografia se limita a desenvolver uma topografia infantil, marcada pela magia das passagens clandestinas e dos esconderijos subterrâneos. Ao contrário do discurso autobiográfico tradicional, determinado por uma cronologia mais ou menos linear, o texto se mantém distante dos condicionamentos temporais e históricos, sendo que cada um dos breves episódios é um lugar dentro de uma mundo infantil que resgata as peculiaridades do espaço da criança, antes de sofrer as imposições da idade adulta.

Berlin Childhood Around 1900 is the “magic” mapping of the first years of an author’s life whose autobiography is reduced to the child’s topography, which is characterized by the magic of secret passages and underground hiding-places. Contrary to the traditional autobiographic discourse, determined by a more or less linear chronology, our text is far from any historical determinism, so that any of the short episodes is a place within a world the rescues the peculiarities of the child’s space, before enduring the impositions of the adult age.

A volúpia de ver: a poesia memorialística de Carlos Drummond de Andrade
Authors: Coutinho Maria Antônia Ramos
Published: July 2015

A poesia memorialística de Carlos Drummond de Andrade- Boitempo I - resulta de uma deliberada perquirição do seu mundo infantil como de um sótão eivado de matéria-prima, à espera de que o olhar o recorte e o gesto criador o plasme. Na seção Morar nesta casa, mais do que evocar objetos pretéritos, como “garrafas de cristal”, “compoteiras”, “licoreiro”, “estojo de costura”, ou se reportar ao prazer sensorial que deles emana, o poeta-colecionador compõe uma vitrine onde se descortinam as impressões quotidianas e subjetivas de uma criança do início do século XX, salvando da perda não só as formas e substâncias obtidas pela reexperimentação poética, mas um modo privilegiado de percepção, no qual o eu funde-se ao objeto e o observador é dragado pela visão espectral que o transforma no objeto mesmo do seu desejo.A partir dessas reflexões, o ensaio A Volúpia de Ver tenta estabelecer aproximações entre a poesia memorialística da infância mineira drummoniana e a Infância em Berlim de Walter Benjamin.

Carlos Drummond de Andrade’s memorialistic poetry Boitempo I is a result of a deliberated search of his child world as a loft full of raw material waiting for the eye that captures it and the creator that moulds it. In the section To live in this house, more than evoking preterit objects such as “crystal bottles”, “compotiers”, “sewing cases”, or reporting himself to the sensorial pleasure that comes out from them, the collector poet composes a shop window where the daily and subjective impressions of a child born in the beginning of the twenty century are disclosed. It protects them from loosing not only their shapes and substances got by the poetic reexperimentation, but also their unique way of perception in which the self is fused with the object, and the observer, dragged by the espectral vision, turns himself into his desired object. Starting from these reflections, the essay The Pleasure of Seeing tries to set up links between the memorialistic poetry of Drummond’s childhood in Minas Gerais and Walter Benjamin’s childhood in Berlim.

Infância e espacialização do bairro judeu nos romances Bom Retiro, de Eliezer Levin e A Guerra no Bom Fim, de Moacyr Scliar
Authors: Cornelsen Élcio
Published: July 2015

Os romances Bom Retiro, de Eliezer Levin e A Guerra no Bom Fim , de Moacyr Scliar, ambos publicados em 1972, retratam a infância nos bairros judeus do Bom Retiro, em São Paulo, e do Bom Fim, em Porto Alegre, respectivamente. Seguindo os passos da tradição literária de autores como Scholem Aleichem, um dos mestres da Literatura Íidiche, Levin e Scliar transportam para o bairro judeu o modus vivendi das aldeias do Leste Europeu, e este processo passa necessariamente pelo olhar das crianças, protagonistas de ambos os romances. Outro aspecto que aproxima os referidos romances é o fato de que, neles, constata-se a relação entre a Literatura e outras Artes: no caso de Levin, o protagonista “amplia” seu universo através das matinês no cinema e das histórias em quadrinhos; no livro de Scliar, o protagonista transfere para o universo do Bom Fim desde imagens chagallianas até super-heróis.

Cross fused ectopic kidney a rare congenital malformation with review of literature
Authors: Shaikh Tanveer Parvez , Ansari Sharique , VU Thahir , Mandhane Nisha , Karandikar Sangram
Published: July 2015

Crossed renal ectopia is one of the rarest urinary system anomalies. It is more often seen at autopsy than in clinical practice. Most cases of renal ectopia remain asymptomatic during life and are diagnosed incidentally. Renal ultrasonography, intravenous pyelography, computerized tomography, and renal scintigraphy (technetium-based tests) are the imaging methods used for diagnosis. Demonstration of crossed renal ectopia is important because it is a predisposing factor for obstruction, infection, and neoplasia of the urinary system. We report male patient who had unremarkable clinical ﬁndings. He had left-to-right inferior crossed renal ectopia with fusion. Surgeons should be aware of ectopic and fused kidneys to minimize perioperative complications because of the uncertain anatomy.

Properties of semi-elementary imsets as sums of elemen- tary imsets
Authors: Kashimura Takuya , Sei Tomonari , Takemura Akimichi , Tanaka Kentaro
Published: July 2015

We study properties of semi-elementary imsets and elementary imsets introduced byStuden´y [10]. The rules of the semi-graphoid axiom (decomposition, weak union and contraction)for conditional independence statements can be translated into a simple identity among threesemi-elementary imsets. By recursively applying the identity, any semi-elementary imset can bewritten as a sum of elementary imsets, which we call a representation of the semi-elementary imset.A semi-elementary imset has many representations. We study properties of the set of possiblerepresentations of a semi-elementary imset and prove that all representations are connected byrelations among four elementary imsets.
Phylogenetic invariants for group-based models
Authors: Donten-Bury Maria , Michalek Mateusz
Published: July 2015

In this paper we investigate properties of algebraic varieties representing group-basedphylogenetic models. We propose a method of generating many phylogenetic invariants. We provethat we obtain all invariants for any tree for the two-state Jukes-Cantor model. We conjecturethat for a large class of models our method can give all phylogenetic invariants for any tree. Weshow that for 3-Kimura our conjecture is equivalent to the conjecture of Sturmfels and Sullivant[22, Conjecture 2]. This, combined with the results in [22], would make it possible to determineall phylogenetic invariants for any tree for 3-Kimura model, and also other phylogenetic models.Next we give the (rst) examples of non-normal varieties associated to general group-based modelfor an abelian group. Following Kubjas [17] we prove that for many group-based models varietiesassociated to trees with the same number of leaves do not have to be deformation equivalent.

Cambios y continuidades de la unión libre en Tijuana, México: el caso de las jóvenes en Tijuana
Authors: Ojeda Norma
Published: July 2015

En México la unión libre o consensual es uno de los arreglos conyugales que ha formado a las familias de procreación por generaciones, y particularmente la unión libre entre mujeres (y hombres) muy jóvenes, con baja escolaridad que viven en zonas rurales. En las últimas dos décadas, este tipo de unión ha ido en aumento; frente a este hecho el presente estudio examina las continuidades y cambios recientes de la unión libre entre las nuevas generaciones del país. Se analiza el caso de Tijuana, B.C., y se considera únicamente a la población de jóvenes adultos entre los 18 y los 29 años de edad. Grupo que forma parte de uno de los contextos sociales más prósperos y abiertos al cambio social en el país, lo cual favorece la independencia económica entre los sexos, especialmente entre los jóvenes. Se utiliza información del Censo de Población y Vivienda 2010 y la Encuesta Sobre Salud Reproductiva de los Adolescentes de B.C., 2006.AbstractThe union libre or consensual union is one of the conjugal arrangements in the formation of families of procreation throughout generations in Mexico. This is particularly the case among women who are very young and have low education among other characteristics. An important increase of this type of union has been observed during the last two decades. This paper analyzes the continuity and most recent changes that the union libre presents among the younger generations in the country. The analysis is based on the case study of Tijuana, B.C. and its population of young adults (18–29 years old), particularly females. This is one of the most prosperous and open to social change social contexts in the country; situation that contributes to the economic independence between the sexes, especially among the youth. The study uses information from the Mexican Population Census of 2010 and the survey Encuesta Sobre Salud Reproductiva de los Adolescentes de B.C., 2006.
Pore Pressure Prediction in Stacked Intercalation of Hydrostatic and Depleted Reservoirs
Authors: Agbor E. , Aguye D.
Published: July 2015

Pore Pressure, also known as fluid pressure, can be defined as the prevailing pressure in the continuous fluid phase of a porous formation. Pore Pressure Prediction is required to carry out well activities in a safe and optimum way. In general, initial Pore pressure regimes in a given field vary from hydrostatic (normal) to over pressureed (abnormal) with increasing depth. As production starts to take place, some reservoirs will become depleted, or sub-hydrostatic.

Prior to drilling commencement, a pre-drill pore pressure prediction is usually carried out by the reservoir engineer, in order to advise the expected range of pore pressure and formation gradient at the top of sand that will be penetrated by the proposed well. There are three classes of reservoir for which pore pressure estimatesd are needed, 1) Unpenetrated reservoir, 2) Penetrated and Undeveloped reservoirs , and 3)Penetrated and Developed reservoir. Predicting the pore pressure in each type carries unique challenges. Predicting pressures in unpenetrated reservoirs often poses great challenges, in most cases; predictions are made by Explorationists, often relying on regional data to model the factors that dictate specific pore pressures in a formation such as burial history, hydraulic continuity, water salinity, overburden etc. The data used to estimate the expected pressures is mainly inferred from reservoirs in analogue fields. Predicting pressures in other reservoir classes depends on a number of factors; data quality and frequency, production and injection performance, cross-flow in depleted reservoirs, etc.

This routine Pore Pressure Prediction becomes very complex when you are dealing with a stacked intercalation of depleted and hydrostatic reservoirs, the vintage of the data used in the prediction is also another area of concern for the subsurface and drilling teams. These pressure regimes (depleted & hydrostatic) pose challenges during drilling and their impact on HSE (potential safety hazards), cost (loosing the well) must be adequately considered and monitored before and during drilling.

This paper presents the methodology (data sources and data screening techniques, reservoir engineering assumptions etc) used to successfully estimate the range of expected pore pressures in a multi-stacked and partially depleted reservoir sequence.

Two case studies are presented;
Research Data Management Practices: A Snapshot in Time
Authors: Kennan Mary Anne , Markauskaite Lina
Published: July 2015

There is increasing pressure from funders, publishers, the public, universities and other research organisations for researchers to improve their data management and sharing practices. However, little is known about researchersâ€™ data management and sharing practices and concerns. The research reported in this paper seeks to address this by providing insight into the research data management and sharing practices of academics at ten universities in New South Wales, Australia. Empirical data was taken from a survey to which 760 academics responded, with 634 completing at least one section. Results showed that at the time of the survey there were a wide variety of research data in use, including analogue data, and that the challenges researchers faced in managing their data included finding safe and secure storage, particularly after project completion, but also during projects when data are used (and thus stored) on a wide variety of less-than-optimal temporary devices. Data sharing was not widely practiced and only a relatively small proportion of researchers had a research data management plan. Since the survey was completed much has changed: capacities and communities are being built around data management and sharing and policies, and guidelines are being constructed. Data storage and curation services are now more freely available. It will be interesting to observe how the findings of future studies compare with those reported here.

Characterization of mechanically milled and spark plasma sintered Al2124-CNT nanocomposites
Authors: Saheb N.
Published: July 2015

In the present work, ball milling and spark plasma sintering were used to
develop Al2124-CNT nanocomposites. The effect of milling time on the grain
size and lattice strain of the ball milled Al2124 alloy powder and the effect
of sintering time and temperature on the grain size of the matrix in spark
plasma sintered Al2124 alloy and CNT-reinforced Al2124 nanocomposites were
investigated. The density and hardness of the developed materials were
evaluated as functions of the sintering parameters. It was found that ball
milling not only reduced the particle size of the Al2124 powder but also
decreased the grain size of the ?-aluminum phase to 50 nm and increased its
lattice strain. A milling time of 6 hours was found to be the optimum time to
reach a nanostructured ?-aluminum matrix. The grain size of the ?-aluminum
phase in the sintered samples increased with increasing sintering temperature
and time to reach maximum values at a sintering temperature of 500?C and a
sintering time of 20 minutes. Although sintering led to grain growth, the
grain size of the ?-aluminium matrix remained in the nanometer range and did
not exceed 150 nm. The relative density and hardness of the sintered samples
increased with increasing sintering temperature and time to reach maximum
values at a sintering temperature of 500?C and a sintering time of 20
minutes.
Argon irradiation effects on the structural and optical properties of reactively sputtered CrN films
Authors: Novakovic M. , Popovic M. , Bibic N.
Published: July 2015

The present study deals with CrN films irradiated at room temperature (RT)
with 200 keV Ar+ ions. The CrN layers were deposited by d.c. reactive
sputtering on Si (100) wafers, at nitrogen partial pressure of 5?10-4 mbar,
to a total thickness of 280 nm. The substrates were held at 150?C during
deposition. After deposition the CrN layers were irradiated with 200 keV Ar+
ions to the fluences of 5?1015 - 2?1016 ions/cm2. Structural characterization
was performed with Rutherford backscattering spectroscopy (RBS),
cross-sectional transmission electron microscopy (XTEM) and X-ray diffraction
(XRD). Spectroscopic ellipsometry measurements were carried out in order to
study optical properties of the samples. The irradiations caused the
microstructrual changes in CrN layers, but no amorphization even at the
highest argon fluence of 2?1016 ions/cm2. Observed changes in microstructure
were correlated with the variation in optical parameters. It was found that
both refractive index and extinction coefficient are strongly dependent on
the defect concentration in CrN layers.
Reduction of solid fuel consumption in sintering of Indian iron ore
Authors: Bhagat R.P.
Published: July 2015

The present investigation deals with the sinterability of Goa (India) iron
ore having high Fe (65.2%) content. The sinter basicity (CaO/SiO2) and its
MgO were varied in the 2.0 to 2.5 and 1.5 to 3.0 range. The effect of process
variables on the quality parameters of sinter namely, tumbler index (TI),
reduction-degradation index (RDI) and reducibility index (RI) as well as the
productivity of sinter was studied. The studies have shown that the
consumption of coke (C: 74%) was inter-influenced by the sinter basicity and
its MgO content. Increasing the solid fuel consumption was not a viable
solution to improve TI and RI simultaneously. The content of coke in the mix
could be reduced to as low as 4% through `low temperature sintering? at the
balanced return fines recirculation (~ 33 wt. percent). The sintering indices
in terms of productivity of sinter and its quality improve quite
significantly at a higher sinter basicity (CaO/SiO2 ~ 2.5) and its lower MgO
content (1.5%).
Influence of Er3+/Yb3+ concentration ratio on the down-conversion and up-conversion luminescence and lifetime in GdVO4:Er3+/Yb3+ microcrystals
Authors: Gavrilovic T.V. , Jovanovic D.J. , Lojpur V. , Nikolic A. , Dramicanin M.D.
Published: July 2015

In this paper, we studied the effects of Er3+/Yb3+ concentration ratio on
structural, morphological and luminescence properties of GdVO4:Er3+/Yb3+
green phosphors prepared by a high-temperature solid state method. The
samples with different concentrations (between 0.5 to 2 mol%) of dopant Er3+
emitting ions and different concentrations (between 5 to 20 mol%) of
sensitizer ions (Yb3+) were studied. The phosphors were characterized by the
X-ray diffraction (XRD), scanning electron microscopy (SEM) and
photoluminescence spectroscopy. For all samples, XRD diffraction patterns
confirmed a formation of a pure GdVO4 phase, while the SEM showed that the
materials are comprised of chunks of deformed particles with an average
diameter ranging from approximately 2 ?m to 8 ?m. Both, down-conversion and
up-conversion emission spectra of GdVO4:Er3+/Yb3+ samples, under near UV and
IR excitations, exhibit two strong emission bands in the green spectral
region at 525 nm and 552 nm wavelengths corresponding to 2H11/2 ?4I15/2 and
4S3/2 ? 4I15/2 electronic transitions of Er3+ ions. The intensity of the
green emission was changed by changing the Er3+/Yb3+ concentration ratio.
This dual-mode luminescence makes these materials ideal as green phosphors
for a wide variety of applications in the fields of bioanalysis and
biomedical.

The laser did not significantly implicate the bond durability in a period of 7 months for both adhesive systems.
Upper Campanian calciclastic turbidite sequences from the Hacımehmet area (eastern Pontides, NE Turkey): integrated biostratigraphy and microfacies analysis
Authors: Sari Bilal , Kandemir Raif , Özer Sacit , Walaszczyk Ireneusz , Görmüş Muhittin , Demircan Huriye , Yilmaz Cemil
Published: July 2015

The upper Campanian (Cretaceous) of the Hacımehmet area (south of the city of Trabzon; Eastern Pontides) is mainly composed of calciclastic turbidites. The basinal unit of the 119 m thick succession includes thin red pelagic limestone interlayers and conglomerates dominated by volcanic clasts. The overlying upper slope and lower slope units of the sequence consist of an alternation of allochthonous calcarenite/calcirudite beds and pelagic marls and mudstones. Calcarenite/calcirudite beds dominate the upper slope unit of the succession and are composed of transported material, including benthic foraminifers, red algae, bryozoan, crinoid and rudist fragments, inoceramid bivalve prisms and neritic and pelagic carbonate lithoclasts. The occurrence of Helicorbitoides boluensis (Sirel) extracted from the calcarenite/calcirudite beds indicates a Campanian age. Identifiable rudists such as Joufia reticulata Boehm, Bournonia cf. anatolica Ozer, Biradiolites cf. bulgaricus Pamouktchiev and ?Biradiolites sp. from the upper slope unit of the succession indicate a late Campanian- Maastrichtian age. The planktonic foraminifers within the red pelagic limestone beds, marls and mudstones throughout the succession consist mainly of Campanian-Maastrichtian forms and suggest mainly basinal depositional conditions. The presence of Radotruncana cf. calcarata (Cushman) accompanied by Globotruncanita elevata (Brotzen) in the basinal unit of the succession indicates an early late Campanian age for the lower part of the succession. Inoceramid bivalves have been collected from the upper part of the succession. The fauna is dominated by ‘Inoceramus’ tenuilineatus Hall and Meek, 1854 and Cataceramus haldemensis (Giers, 1964); other taxa recognised are: ‘Inoceramus’ algeriensis Heinz, 1932, Platyceramus vanuxemi (Meek and Hayden, 1860), ‘Inoceramus’ cf. nebrascensis Owen, 1852, Cataceramus aff. barabini (Morton, 1834), Cataceramus gandjaensis (Aliev, 1956), and ‘Inoceramus’ sp.; the assemblage indicates the ‘Inoceramus’ tenuilineatus Zone; corresponding to the middle-late Campanian boundary interval. The uppermost part of the succession is characterized by the presence of the trace fossils Scolicia strozzii and Scolicia isp., indicating a mixed Skolithos-Cruziana ichnofacies. This ichnofacies suggests a well-oxygenated environment.
Rehabilitation and strengthening of Sylva Bridge at Kungur, Russia
Authors: Timofeev Michael , Geyzen R.
Published: July 2015

Sylva Bridge at the downtown of city Kungur is one of the oldest road bridges in Perm region, the West Urals, Russia. Its erection was begun in 1912 and was interrupted with the First World War and the further events in Russia. The bridge was opened only in 1931. For 75 yeares of bridge operation the most part of bridge constructions have been acquired plural damages, both mechanical and corrosion. After the bridge inspection in 2003 and according to the calculations of its capacity, the decision on reconstruction of the bridge was accepted. The purpose of rehabilitation was to replace the timber deck by steel orthotropic deck with asphalt pavement. A new deck was to be engaged in combined action with the existing metal structures with the help of socles with highstrength bolts. Due to this, the bridge carrying capacity was to be increased as required with the modern standards. In 2006, after tests, the bridge was opened for traffic.

Critical aspects in designing earthquake-resistant dual systems
Authors: Mezzi Marco , Comodini Fabrizio
Published: July 2015

A simple scheme of dual system is designed for different seismicity levels according to Italian and European standard codes. Some critical aspects on the application of the capacity design rules are evidenced. Nonlinear analyses are carried out for evaluating the actual lateral behavior, showing that the actual structural performance can significantly differ from that assumed at design level. The constructive detailing prescriptions appear to be not calibrated on the design performances and local ductility demand expected in dual systems. This can lead to over-strengthening the structure, without reference to the design assumptions, the actual site hazard, the standard safety levels.

A Two-Stage System Identification of Truss Bridge from Limited Measured Static Responses
Authors: Bandyopadhyay D. , Majumdar A. , Sengupta S. , Roy S.
Published: July 2015

System identification of Structures has become significantly important, particularly in the context of safety, timely intervention for maintenance and to exploit better usefulness in future. Truss bridges are suitable for moderate spans and were extensively used in railways. However, the condition of these age-old bridges became essentially important to assess for safety and reliability. A lot of research activities mostly adopting inverse dynamic approaches have been attempted to identify the structural system. The requirement of incorporating sophisticated instrumentations and efficient numerical techniques of the mathematical problems is complex and may not be feasible due to some practical constraints in many situations. System identification of structures based on limited static responses is simple and seems to be an attractive proposition. But, the accuracy of the predicted structural properties depends on the location of measurement degrees of freedom (MDOF) & amount of data used. A system identification technique with limited static responses at selected MDOF based on sensitivity analysis is studied in this proposed paper. The two-stage analysis processes include selection of measured degrees of freedom (MDOF) from sensitivity analysis and subsequent identification of structural parameter of truss is developed and studied. The structural property is identified at the element level using applied forces and corresponding measured displacement at those sensitive MDOF as selected. The proposed method seems to be efficient and suitable for practical problems of truss bridges, as it is able to identify the structural damage from limited measured data.

Compared with the traditional suspension bridge, the Songhua pedestrian bridge has no hangers, and the cable is under the stiffening girder in the mid-span position. The loads of human groups on the floor system are transferred to the cable by the brace strut of curve shape. This paper mainly introduced the structure design, the related parameters, the construction method，and the static and dynamic analysis. In the static analysis, the cable’s internal force and the stress characteristics of the stiffening girder have been discussed. Regarding the dynamic analysis, this paper compared the bridge’s natural vibration characteristics under different boundary conditions of the stiffening girder and the earthquake resistant behaviour and calculated the vertical acceleration by time-history. The results shows that fixing the two end of the stiffening girder can improve the natural frequency efficiently so as to avoid the happening of resonance.

A main objective of the present investigation is to obtain structural responses of a continuous box girder bridge employing a diagnostic load test. The bridge under consideration is a 7-span, prestressed concrete structure with the total length of 665 meters. Four 3-axle trucks are employed in the diagnostic load test. Strains and vibratory motions of the girder are measured and reported. Varying speeds of test trucks are considered during the dynamic test. Natural frequencies and mode shapes of the box girder are determined based on modal analysis. Correlation between natural frequencies of the box girder obtained from field measurement and a finite element model is also illustrated. Wavelet analysis is employed to decompose girder strains into static and dynamic components, and dynamic amplification factors are determined and reported. In addition, the results of long-term measurement of pot bearing movements subjected to variations of surrounding temperature are also presented.
Elegant and safe structures made of glass
Authors: Siebert Barbara
Published: July 2015

Glass becomes more and more popular for applications in building structures. Examples are facades, large overhead glazing's and constructions completely made of glass. On the one hand side the architect wants to design an elegant and transparent structure; on the other hand side the engineer wants to design a robust and safe structure. It is possible to fulfil these two demands. Glass is a brittle material, so it is important to design very careful - for both: the architect and the engineer. So many points are important for the design: The details, the background of the theory of glass (structure mechanics), a close to reality Finite Element analysis, and often testing of glass to guarantee a sufficient remaining load carrying capacity.
Utilitarian to Aesthetic: The Evolution of Base Isolation
Authors: Martini Kirk
Published: July 2015

The paper examines the evolution of base isolation from its early utilitarian applications to its later applications that enabled elegant aesthetics in landmark works of architecture. The early implementations of base isolation arose from three motivations: providing high performance for emergency facilities; providing higher-than-code performance as desired by a building owner; or retrofitting historic buildings. The opening of Toyo Tto's Sendai Mediatheque in 2001 marks an important milestone in the evolution of base isolation, since it introduced a new motivation: architectural aesthetics in a new building. Mediatheque employed base isolation to enable a visually striking structural system. Tto's TOD's Omotesando building, and the Tama Art University Library also use base isolation in this manner. Base isolation has evolved from a utilitarian technology to an aesthetic device to achieve architectural forms not otherwise be possible in a strong seismic region.
Experimental investigation and FEM simulation of a bridge pier with scoured pile foundation from shaking table tests

Published: July 2015

This study investigated the seismic performance and soil-structure interaction of scoured bridge pier models with pile foundations by shaking table tests and finite element simulations. The model bridge pier with a pile foundation comprised of a lumped mass representing the superstructure, a steel pier, and a footing supported by a single aluminium pile within dry silica sand. The performance of the structure was discussed for different scoured conditions. Tt is found that the transition of moment demand from pier to pile with increasing exposed length may cause the bridge to failure. A three-dimensional finite element model of the shaking table test was created using the ANSYS program. The soil dynamic property was taken into consideration for the nonlinearity of the soil-pile interface, and an equivalent linear model was used for the soil behaviour. The computational model was validated by the data obtained from the shaking table tests.

An Innovative Concept for Pre-stressed Glass Beams
Authors: Weller Bernhard , Engelmann Michael
Published: July 2015

At Technische Universität Dresden structural glass researchers are developing an innovative concept for pre-stressing glass beams. These beams are post-tensioned by unbonded cables which are anchoraged at the beam ends. Four different cable layouts are chosen to investigate on an optimized global load bearing behavior and depend on the expected external bending loads and the chosen construction especially in terms of the supports and the connection to the glazing.

To increase the loadbearing capacity as well as the post fracture behavior reinforced glass beams in multiple applications may be post-tensioned. An embedded steel cable as it is known from the principles of reinforced concrete design is tensioned creating an internal constraint. This will result in a compressive stress constraint state in the glass. Additionally, the deformation of such a beam may be affected as needed before an external bending load appears.

Nevertheless, glass beams are subject to imperfections. Due to this initially unknown deviation from the theoretical perfect state the applied axial force from post-tensioning the beams will induce additional torsion as well as further bending moments. This may result in an unfavorable deformation of the glass beam during the post-tensioning process and increase the risk to suffer from early failure such as lateral torsional buckling.

The results of the experimental investigation in terms of load-cable force and load-deformation relations caused by four-point bending are shown and analyzed. Furthermore, the deformation behavior is compared between the different cable layouts leading to a conclusion what construction is most suitable to be post-tensioned from the perspective of this very load case. The project was funded through the German Federal Ministry of Economics and Energy (BMWi).
Influence of Edge Design and Location of Load Introduction on the Loadbearing Capacity of Glass
Authors: Neumer Daniel , Siebert Geralt
Published: July 2015

The common cause of glass failure are cracks originating at the glass edges. This circumstance becomes even more significant for load bearing glass structures, because external loads are normally introduced to the glass edge. This requires an optimisation of the support conditions. In this paper two factors involved in this problem are highlighted: the edge design and the location of the load introduction. This paper shows the first results of a research project.

Published: July 2015

The Ferrara waterway, connecting this historic town with Comacchio on the Adriatic Sea is being upgraded: section widening and straightening as well as higher clearance has called for the replacement of most of the existing bridges. On the outskirt of Ostellato the conditions were appropriate for a medium span stay cable road bridge having the peculiarity of a curved girder with a plan and crest radius of 1000 metres. The structure had to be cost efficient, because it was offered as an alternative design to an awkward but smaller tender solution within the same budget. Concrete towers had to be of the inverted Y shape to resist lateral forces given by the horizontal radius, steel frames have been cast into the upper concrete section of the towers to facilitate positioning and erection of the 48 stays. The 14m wide deck sports the classical composite design with plated girders running at both sides and transverse beams at 4 metres centre; with an height of 1.5m circa for the 130 metres span, the resulting slenderness is considerable and associated with the double curvature gift the structure with elasticity and lightness.

In this paper, we systematize various types of diagonal structural systems, including trusses, from the viewpoint of structure and form. First, based on the concept that a diagonal structural system consists of fundamental elements, we outline unit models as minimum elements. Then, in order to classify the patterns of constitution of the system, we present the formation flow of a three- dimensional structure and the application of a diagonal structural system to such a structure.
Refurbishment of the concrete-glass windows of Aachen City Hall
Authors: Geßner Stephan , Rempel Sergej
Published: July 2015

Textile-reinforced concrete, an innovative composite material, creates new opportunities for the refurbishment of historic buildings. For example, particular filigree components, such as the historic concrete glass windows of the Aachen City Hall, would benefit from the corrosion-resistant carbon textile reinforcement. The 60 years old windows had to be repaired because of the corroded steel reinforcement and concrete spalling. Therefore, the glass pieces embedded in the concrete were separated and reinstalled in reconstructed concrete-glass windows. The steel reinforcement was replaced by carbon reinforcement. Thus, the historic monuments protection authorities' terms were respected while avoiding future corrosion damage.
