title: Moment Amplification Factor of Beam-Columns with Initial Deflection

description: The maximum bending moment occurs in the midlength (second-order moment) in a simply supported beam-column subjected to compression and end moments, depending on the slenderness ratio and the level of the axial force. In AIJ Recommendation for Limit State Design of Steel Structures, the second-order moments are evaluated by multiplying an amplification factor by the first-order moments. The amplification factor of linear elastic beam-columns can be calculated, however, the initial deflection was not considered.In connection with the design method of steel beam-columns, objective of this study is to clarify the dimensionless factors which define the amplification factor and the effect of the dimensionless factors on the amplification factor is discussed.The analytical model is the simply supported linear elastic beam-column subjected to axial force and end moments. The amplification factor is obtained by solving the differential equation. It has found that parameters which affects the amplification factors were the initial deflection, the axial force ratio and the ratio of end moments. The analysis was carried out with these parameters. It has become clear from the analysis that: 1) the amplification factors increases as the amplitude of the initial deflection increases and 2) the maximum bending moment is not always equal to the end moment, which is the first-order bending moment, when the moment distribution is anti-symmetric bending and the initial deflection is considered.

title: Experimental Study of Restrained Steel-Concrete Composite Beams under Cyclic Loads

description: Composite structures is made from steel connected with slab concrete holding together with shear connectors. This facilitates in loading capacity according to AISC and AASHTO standard design. The test on restrained steel-concrete beams under monotonic loading and cyclic loading condition is with the fully composite and the partially composite. The result of this research is that the fully composite is more loading capacity than the partially composite. Moreover, the study also focuses on the deformation capacity ratio between the fully composite and the partially composite under both mentioned conditions. In this aspect , it is found that the deformation capacity of the fully composite is less than the partially composite. From the study, it is suggested that the steel concrete composite be design for the fully composite because it can hold the highest strength, prevent slipping between steel and slab concrete , and increase the durability.

title: Rehabilitation of Box Girder Bridge

description: A large pre-stress continuous box girder bridge consists of two separate parts, ten spans deck and eight spans deck. The bridge was subjected to multiple airstrikes, which caused several damages. The most serious are the complete destruction of four conductive spans in the ten spans deck, the movement of the remaining six spans longitudinally by about (1.25)m and transversely by about (0.1)m. Local damages occurred in other parts of the deck structure and minor damages in the piers and abutments. The deck structures were constructed by incremental launching method (ILM). Rehabilitation of the bridge included repair of the local damages, lifting and re-instatement the six spans, which weighs about (9000) tons, to its original position, the constructing and launching of new box girder to substitute for missing spans, and finally connecting old and new spans effectively. This paper introduces briefly the re-instatement of the six spans, connection details between the old new structures, then assessment of efficiency of the connection by performing analysis and load testing the connecting span.

title: Wind load perdition of large-span dry coal sheds based on GRNN and its application

description: The distribution and fluctuation of wind load on large-span dry coal sheds are complicated. Wind load on typical shape of roofs can be sometimes determined based on the wind tunnel tests carried out on roofs of similar shape. To expand the application scope of the test data, Generalized Regression Neural Network (GRNN) is introduced. The prediction models on large-span dry coal are given, where the wind load is expressed by 8 parameters: mean, RMS, skewness, kurtosis of wind pressure coefficients, three auto-spectral parameters (including descendent slope in high frequency range, peak reduced spectrum and reduced peak frequency) and coherence exponent for cross-spectra. Cross validation and trails are carried out to determine the parameter in the GRNN model. Further, the wind load prediction is applied on a dry coal shed shell. The wind-induced responses are calculated and compared with the results of wind tunnel tests. The results are even close. Therefore, it can be concluded that GRNN is feasible in predicting wind load on roof structures.

title: Calculation of the labor consumption rate for shuttering works whilst considering uncertainties

description: Calculating construction costs and times is one of the most important and demanding tasks in construction management and economics. To arrive at a realistic calculation base, valid data and information is constantly being sought for labor consumption rates, output rates, productivity, material consumption, volumes in stock, number of transport cycles, and cost and time parameters that must be estimated or calculated ex ante. Ultimately, final cost and time parameters must be determined on the basis of such considerations and calculations. Accurate figures must be stated or submitted at the end of any analysis. These depend on the complexity of the building and on the conditions prevailing at the actual work stages and rely on more or less uncertain input data. One possible solution to this issue is to consider ranges that can deliver final conclusions on determined values. To systematically consider ranges in input parameters, this paper concentrates on applying probabilistic calculation methods based on Monte Carlo simulations. Key outcomes of probabilistic calculations include histograms that are used to directly capture the chance/risk ratio relative to a specific (selected) parameter. This paper presents a practical example of calculating the labor consumption rate for shuttering works to highlight the significance of the chosen chance/risk ratio and to show how it can be integrated into the systematic decision-making process adopted by the parties involved in the project.

title: MECHANICAL PROPERTIES OF COCONUT FIBER-REINFORCED CONCRETE

description: The use of natural fibers in concrete has significantly increased in recent years as a result of the push for sustainable construction. Coconut fibers, also known as coir fibers, have been used as natural fibers in concrete, particularly in some parts of Asia. This paper presents an experimental study that investigates the use of coconut fibers in concrete. Two baseline concrete mix designs were selected based on design standards with a water-cement ratio of 0.4 and 0.5 respectively. For each baseline mix design, four 20 cm x 20 cm x 1 cm concrete plates were constructed by varying the percentage of coconut fibers by weight of cement. The fiber contents studied are 0%, 0.1%, 0.175%, and 0.25%. The concrete plates were then tested to determine the mechanical properties of the coconut fiber-reinforced concrete and comparisons were made with the mix designs with 0% coconut fiber content. The results show that adding coconut fibers increases the flexural strength of concrete plates. This is particularly beneficial for low scale construction applications such as those in concrete tile production. For both mix designs, adding 0.25% of coconut fibers increased the flexural strength of the concrete plates by 90% when compared to concrete with no coconut fibers.

title: The static behaviors and numerical prediction on displacement of an existing arch dam

description: In order to estimate the seismic safety of existing arch dams, it is essential to assess the static behavior and the mechanical resistance of arch dam. Numerical analysis model for transverse joints (contraction joints) of the arch dam is developed considering the separation, sliding and re-contact behaviors of contraction joints. The static behaviors of an arch dam under annual change of temperature and water level were calculated by using non-linear three-dimensional finite element analysis method that incorporated the developed numerical analysis model of contraction joints. The displacement of the dam body was compared both in analysis and in measured data. At a result, the calculated results can give a good estimation for dam deformation of an existing arch dam caused by those loads. In addition, the effective arch zone was formed under consecutive contraction joints. Thus, the nature of load capacity mechanism was identified. Using these calculated results, the numerical prediction on the displacement of an existing arch dam was proposed for daily management.

title: INTERFERENCES BY THE APPLICATION FOR THE CHARGES BY USE OF RAIL INFRASTRUCTURE IN EUROPEAN INTEROPERABILITY

description: The European Union adopted a series of destined Directives to convert the rail sector in a way of competitive transport, giving place to the separation of activities of administration of the infrastructure of the own activities of the exploitation, the opening of the rail transport in diet of free competition and the allocation to the administrator of rail infrastructures of the necessary functions for the provision of services regarding transport of travellers as of commodities. This remained reflected in a series of charges, in which each country created some specific rules of fixation of canons and that has given place to prices very diverse, no only economically but also to the hour to define the same, resulted of the nonexistence of a guideline detailed of how would have to fix the same. This opening forces to the rail companies to fulfil a series of legal requirements, technicians and economic to be able to operate by the European rail network. The economic requirements remain reflected in a series of canons to credit to the administrators of rail infrastructure of the countries by where circulates a rail transport. These canons, although they are regulated by the corresponding European Directive, are established according to the rule of the country, what gives origin to a diversity of the same.

title: Effect of Recycled Materials on the Tensile behaviors of Steel Fiber-Reinforced Cement Composite

description: Conventional cement composite is generally produced with ordinary Portland cement (OPC) as a binder. However, during manufacturing the cement composite, large amount of carbon dioxide (CO2) are emitted. Therefore, recycled materials such as fly ash and recycled fine aggregate are proposed to be respectively replaced to OPC and natural sand in order to reduce CO2 emission of cement composites. For reinforcing fibers, micro steel fibers were used. For investigating mechanical properties of steel fiber-reinforced cement composites (SFRCCs), direct tension tests were conducted. The test results showed that fly ash improves tensile strength and ductility of SFRCCs. However, tensile strength of the SFRCC decreased as replacement ratio of recycled fine aggregate increased. The use of recycled materials in FRCC helps to save natural resources and promote sustainability in civil engineering materials.

title: THE REINFORCED CONCRETE BEAM DEFLECTION AND CRACKING BEHAVIOR WITH ADDITIONAL FIBER STEEL

description: The classic theory mentions that the assessment of deflection and crack width should be taken to minimize those two behaviors. This research itself has the objective to examine whether the additional fiber steel and increased reinforcement ratio has any significant impact on the deflection and existing crack width. This test used the reinforced concrete beams with a size of 15 cm x 25 cm x 180 cm which placed on a simple pedestal. The test was done gradually in every 108 kg until the reinforced yield reached. The fiber increased from 0%, 1.57%, 3.14% and 4.71% while the performance rebar ratio increased from 2 # 10, 2 # 12 and 2 # 14. The result shows that additional 4.71% of maximum fiber decrease compressive strength and rupture modulus while the tensile strength increased. The additional fiber reached a maximum in 4.71% and the additional diameter of 10 mm, 12 mm, and 14 mm increased the deflections and crack width.

title: CORPORATE FINAL NODAL DESTINATION CHOICES IN THE EXODUS FROM JOHANNESBURG CENTRAL BUSINESS DISTRICT

description: The opening up of the invisible barriers after the fall of apartheid in South Africa led to massive internal migrations and relocations to bigger cities. Johannesburg as the biggest economic hub not only in South Africa but in Africa pulled the majority of the new opportunity seekers from even across Africa. This uncontrolled influx led to overcrowding, increased crime and grime in the city centre of Johannesburg. The loss of value of property in this part of the city led to a lot of corporate organizations relocation to budding economic nodes in and around Johannesburg. The study seeks to understand the processes that were applied in deciding the suitable new Headquarters for these blue chip companies. The new nodes that took in the new relocators have over time assumed their own identity in terms of the type of companies that are mostly found in these areas. Although these identity nuances are not pronounced at first glance they are accentuated with greater scrutiny. The study sought to see if there is a fit between the independent observation of the characteristics of these locations and the perceived attractors to the blue chip firms. This was achieved by interviewing the executives and sending emails to some in order to understand the processes and triggers affecting their decisions. It was generally observed that prestige and locational characteristics that complemented the company's ethos were the overriding triggers in deciding on the final nodal destination.

title: COMPUTATIONAL APPROACH FOR ESTIMATING HYGRIC PROPERTIES OF HETEROGENEOUS MATERIALS IN LONG-TERM ASSESSMENT OF MOISTURE-INDUCED DAMAGE

description: Long-term assessment of degradation processes is a very useful tool for an analysis of building materials performance. Since computational techniques are mostly used for this purpose, hygric properties of involved materials are required as substantial input data. Unfortunately, some construction details or heterogeneous materials have to be solved by means of multi-dimensional modelling which is demanding on computing power and thus the calculations may take a lot of time. The presented paper aims at determination of effective hygric properties of heterogeneous materials which would allow one-dimensional transformation. The parameter identification process is carried out on the basis of results of multi-dimensional modeling, using genetic algorithms. The main objective is to find such effective global moisture transport and accumulation functions that provide in one-dimensional modeling as similar results to multi-dimensional modeling as possible. The obtained functions give a very good agreement; the investigated relative humidity profiles differ only by 1.48 percentage points in average. The correctness of obtained results is also verified using the Lichtenecker

title: Factors Affecting the Selection of Contractors in Green Building Projects

description: The growing interest in sustainable design and construction introduces new set of risks specific to green building projects. One of the challenges in green building projects that requires special consideration is the selection of the appropriate contractors to ensure that the targeted sustainability goals of the projects will be achieved. Rapid growth of green building movement requires that contractors that are willing to be active in sustainable construction learn green building rating systems, application processes, green products, and related laws and regulations. This study investigates major factors affecting the selection of contractors that will be responsible for the construction of projects aiming certification through green building certification systems. An extensive literature survey was completed to identify the significant factors in the selection process, which are important for the successful completion of the projects. It is found that experience in green building projects and certification system procedures, managerial approach, technical approach, price, past performance, and qualification are important in the selection of contractors in green buildings.

title: INNOVATION SCENARIOS FOR THE TECHNOLOGICAL DESIGN OF THE OPERATING SUITE: Design criteria and methods

description: Today the operating suite is considered, together with the diagnostic unit, the functional area that is more subject to profound changes, resulting in an increased technological complexity. The road paved by the new approaches to care and illness imply that the coming years will be characterized by a profound and radical change of the medical-scientific knowledge and even more so of the diagnostic and therapeutic methodologies. This paper analyses the characteristics of existing healthcare facilities, with respect to the needs created by the new role of the hospital, as well as the impacts on the more complex and rapidly changing sectors. The identification of the problems and the definition of the number of needs will allow to outline the strategies to adopt for the design of a modern operating suite, defining the basic requirements for an optimum supply of the service. The objective will be to define useful design criteria and methods to favour the inclusion process of innovative factors, so that the building unit can promptly respond to any evolution of needs, overcoming the now consolidated spatial and functional obsolescence that has characterized it lately.

title: Experimental study of Ultra-High Performance Fiber Reinforced Concrete dosages with ultra fast setting time

description: The overall objective of the work is the development of ultra high performance fiber reinforced concrete (UHPFRC) dosages, with ultra fast setting time, that can be used for shotcrete.In this study, a number of UHPFRC mixtures with different amount of admixtures (plasticizers and accelerating) and different mixing time were tested, to increase either the rate of stiffening or setting of the concrete or the rate of hardening and early-strength development. Workability, consistency and mechanical properties of UHPFRC including compressive and flexural strengths at different ages were assessed. Results showed mixtures than begin their first setting in less than 1 minute, with very good mechanical properties in 24 hours, and without reducing the compressive strength at 28 days. From the results obtained, various uses of these mixtures are proposed taking into account, the new context of the Construction field, with the appearance of new placing concrete techniques.

title: Critical Comparison between two Strengthening Techniques of Reinforced Concrete Columns

description: In this work a comparison between different methodologies for the strengthening of concrete is made. In particular both concrete confined with FRP and concrete confined with angles and battens are considered. By comparing these two methodologies, it appears clear that a lot of limitations arise when FRP are used, in particular when the shape of the reinforced section is constituted by a rectangle having the ratio between the two sides that is greater than two. In fact, in this case the confining action due to FRP is negligible, while by means of steel bars passing through the section the use of traditional reinforcing methodology can be very effective. In addition to the confining effect, the angles can provide strengthening both in tension and in compression, depending on the structural detail adopted at the concrete floor slab.
