Authors: Briseghella Bruno , Shi Jinhua , Xue Junqing , Huang Fuyun , Miao Jianbao , Wang Xu
Published: August 2023

The deck expansion devices installed at the abutment can be eliminated by using the concept of the semi-integral abutment bridge (SIAB) to improve the serviceability and durability of the bridge. The mechanical performance of the girders in the SIABs with continuous structure or continuous deck between adjacent girders could be different. To investigate the different response of the two bridge typologies, a SIAB built in China was chosen as a case study. A finite element model (FEM) established by using the MIDAS-Civil software was used to compare the mechanical performance of the continuous structure SIAB or continuous beck SIAB under different load cases. The influence of different girder connection types and bridge lengths on the mechanical performance of a multi-span SIAB was studied. The results showed that the influence of the girder connection types on the internal force of the girder of a two-span SIAB is significant. Compared with the continuous structure SIAB, the absolute bending moments of the girder at the pier top, end diaphragm and mid span of the girder in continuous deck SIAB are lower, however, the shear forces of the girder at the pier top and end diaphragm are higher. With an increase in the bridge length, the continuous structure SIAB is more sensitive to the temperature variation than the continuous deck SIAB. The maximum lengths of the multi-span continuous structure SIAB and the multi-span continuous deck SIAB is 26 m (two-span) and 52 m (four-span), respectively.

Published: August 2023

European countries are characterized by an extensive infrastructural network, mainly built around the 1960s and 1970s. In that period prefabrication processes were starting to gain ground, and one of the most spread and studied typologies of bridges was constituted by reinforced or prestressed concrete decks. Those structures have gone through years of service, which caused the inevitable degradation of the materials. Moreover, the design and construction processes of that period have soon become obsolete, and the knowledge relative to the influence of detailing increased significantly. One particular element that has been commonly used has been the half-joint, which is easy to prefabricate and has a strategic impact. However, in recent years this solution is showing critical aptitudes in resisting structural degradation and material decay. Besides, Structural Health Monitoring (SHM) strategies are gaining attention since they are a very useful tool for gathering information on the current state of the structure and then for evaluating intervention plans to improve safety. Indeed, existing bridges, despite their working age, are still crucial to the development and sustainability of community life, and their decommissioning would be an act of critical impact on the communities (e.g., economy, logistics, sustainability). This contribution presents the design, the simulation, the implementation and the preliminary results of laboratory tests on half-joints in reinforced concrete beams that will be developed at the Politecnico di Torino in connection to CPM Samarate. They are designed to test and compare different monitoring techniques along with different steel reinforcement configurations.

Published: August 2023

The paper provides a summary and description of the geotechnical earthquake engineering aspects related to the detailed design and construction of the record-breaking 1915 Çanakkale suspension bridge with a 2023 m long main span, 770 m long side spans and approach bridges of 365 m and 680 m. The main steel bridge foundations comprise two concrete caisson foundations placed on soil improved by steel pile inclusions, two gravity-based concrete anchor blocks and two side span piers founded on bored piles. The post tensioned concrete approach bridges are supported by piers on bored piles, which – where needed – are seismically protected by ground improvement consisting of deep soil mixing. The paper briefly describes the main features of the seismotectonic setting and the derivation of the effective input motion used in the bridge global structural model. The derivations of the foundations’ dynamic impedances and the link to the site response are described. The design and construction of the foundation systems, consisting of both soil improvement and the foundation elements themselves, and the interaction with the site response analysis, the liquefaction hazard and lateral soil deformation assessments are described. 2D nonlinear time history analyses for the evaluation of the ground (slope movements and the derivation of kinematic forces on the piles supporting European and Asian approach bridges and side span piers are also illustrated. Finally, a brief description of the monitoring system related to geotechnical earthquake response and its rational is presented.

Authors: Geier Roman , Mack Thomas
Published: August 2023

To the north of Bangkok (Thailand), a new motorway section has been realized in recent years to relieve the surrounding routes in Nonthaburi Province, whose main characteristic is an extradosed bridge over the Chao Phraya river with a total length of 460 m. The building consists of two pylons with golden dome and 96 stay cables carrying a box girder cross-section designed for six lanes across the river. To monitor the structural behavior of the bridge an extensive monitoring system was awarded by the client to DYWIDAG Systems International GmbH in cooperation of Schimetta Consult who have optimized, designed and realized the system. In total 45 sensors are monitoring permanently temperatures, strains and deflections of the bridge, inclinations of the pylons, movements of the expansion joints, wind velocities, accelerations and cable forces. The data are automatically stored on site, provided via a UMTS connection to an external server within a few minutes, enabling continuous display of the signals on a homepage for easy access by the client In addition, the measurement data are being summarized on a half-year base and the results are submitted to the clients by a measurement report. The monitoring system is continuously acquiring data since opening of the structure to regular traffic, enabling a very good insight to the structural behavior.

Published: August 2023

With a world record main span length of 2023 m the design of the 1915 Çanakkale Bridge spanning the Çanakkale Strait, Türkiye, warranted an extensive array of aerodynamic investigations carried out for determination of the wind loading and verification of the aerodynamic performance. Also, the paper reviews the development of the design specifications considering the location of the bridge and available meteorological data. The development of the wind tunnel test programme necessary to verify the specifications and obtain input to the bridge design is reviewed and selected key results presented. The wind tunnel tests discussed included section model tests of the bridge girder and towers, full aeroelastic models of the free-standing tower and full bridge in service and section model tests of the hanger cables for clarification of rain / wind and vortex induced vibrations. Concerning flutter stability of the bridge it was found that the twin-box girder design provided a high critical wind speed for onset of flutter linked to the progress of the aerodynamic moment coefficient. Vortex induced vibrations of the hanger cables were found to be less pronounced than proposed by Eurocode whereas rain / wind vibrations were substantially stronger.
Experimental and numerical study on the re-anchoring of wire in grouted prestressed tendons
Authors: Aparicio Jonas , Hoang Tien , Cumunel Gwendal , Foret Gilles , Jeanjean Yannick , Saint Martin Julien Castres
Published: August 2023

Some recent researches have focused on strand wire damage in external prestressing tendon. When some strand wires of a grouted prestressing cable are damaged, the tension in the cable can be preserved due to the re-anchoring phenomenon. For safety issues, it is important to study the damage limit that a tendon can suffer before the rupture. While the re-anchoring of a strand is well studied, there is less literature on wire re-anchoring. In this study, we tested grouted seven-wire strands which are put under tension and then cut out wire by wire to simulate the wire damages.

The re-anchoring is observed by strain gauges installed in the strands and on the sheath. In addition, a numerical model has been developed with the help of FEM to analyse the mechanical phenomenon during and after the wire cuts. The results show that the tendon is bent and twisted because of the loss of tension and moment when one or several wires are cut off. Moreover, the strand strain is various following the gauge position in each wire and its distance to the cut section. This result contributes to the comprehension of the wire damages in grouted tendons, and could be extended to grouted multiple-strand tendons.
Normandie Bridge – Fatigue Analysis and Innovative Instrumentation of the Orthotropic Steel Deck
Authors: Roibert Adrien , Virlogeux Michel , Fasquel Clément , Maherault Jean-Philippe
Published: August 2023

The main span of the Normandie Bridge includes a 624-meter-long central steel section with an orthotropic steel deck. This deck is subject to the effects of the road traffic, which governs the fatigue resistance of welded joints. The Chambre de Commerce et d’Industrie Seine Estuaire (CCISE), concessionnaire of the bridge, led a study combining classic analyses based on existing codes and on an innovative instrumentation.

The analysis performed on the orthotropic deck of the Normandie Bridge combines an approach by computation, conducted on a finite element model, with an innovative physical instrumentation using Distributed Fibre Optic Sensors (DFOS).

The so-called "distributed" optic fibre allows to use the fibre not only as a conductor, but also as a sensitive element to measure deformations. It makes possible to measure deformations, and thus stresses, at very small intervals, every 2.6 millimetres in this case. The fibre can thus be considered as a “linear” sensor, installed on ten troughs per fibre, being bonded directly to the welds. From the recorded stresses it can give a direct evaluation of the fatigue damage and of the residual life of the deck.

This study evidences the interest of an experimental evaluation of the fatigue damage in existing structures, and provided an interesting and sometimes unexpected feedback on design practices of orthotropic steel decks.

It also highlights the predominant influence of the very local traffic conditions on the fatigue damage, such as the precise relative position of the axle wheels and of the welds, that the actual codes (Eurocode or other) take into account very imperfectly, and that cannot be compensated for by the quality of calculation models.
From Leonardo da Vinci to Fritz Leonhardt – The Role of Physical Measurement Models in Bridge Engineering
Authors: Schmid Benjamin , Weber Christiane , Wenzel Baris , Möller Eberhard
Published: August 2023

Since ancient times, physical processes have been explored with models to understand the laws of nature. In the late 15th century Leonardo da Vinci researched the behaviour of bending of elastic beams of various spans using physical models. Later, in the 20th century, physical models were indispensable for civil engineers and architects to check the load-bearing capacity of unconventional and innovative structures. Even today, physical models are used in different engineering disciplines, for example, to test the behaviour of long-span bridges in wind tunnels. This paper attempts to give an overview of important testing facilities which achieved technological progress in the field of bridge engineering. The models built and the tests performed in these facilities will be used as examples and will answer the question of the critical role these models played in the planning and construction process. The authors are collecting information and are analysing these physical measurement models in the current research project, “Last Witnesses”, funded by the German Research Foundation (DFG) to replicate some of them as digital twins. The results will be available to the public in an openly accessible database.

The size of the north anchorage caisson of Wufengshan Yangtze River Bridge is 100.7×72.1×56m, which is the largest caisson project in the world. The size of the south anchorage caisson of Oujiang North Estuary Bridge is 70.4×63.4×67.5m, which is the first large caisson project built in deep soft soil in the world. During the construction of the above two large open caisson projects, the research and practice of new theories, new methods, new processes, new equipment and other construction technologies have been carried out. The main innovative technologies are as follows: (1) The mechanism model of "effective stress-water content-bearing capacity" has been proposed, and the optimization algorithm of sand pile composite foundation based on change of water content is proposed, which has solved the problem of temporary foundation treatment of large open caisson. (2) The deflection control method of large open caisson is put forward to realize the quantitative safety control of large open caisson structure. The excavation and sinking technology of "semi rigid-multi node-full node-partition" multi-support system transformation has been developed to ensure the safety of the caisson construction structure. (3) Four cutters suitable for high viscosity and high bearing capacity strata, mobile rapid soil taking equipment and graded cutting anti-paste drill bit are invented to realize efficient soil taking construction. (4) The double index early warning method of soil gushing control and rapid sinking of caisson is proposed, which reduces the risk of caisson construction.

Published: August 2023

This study proposes a rapid post-earthquake damage assessment technology for regional bridges based on nonlinear dynamic time-history response analysis. Compared with the traditional method based on vulnerability curve, the method proposed in this paper can comprehensively consider the structural design parameters and time-frequency characteristics of ground motion, and can quantitatively evaluate the damage state of bridges. This study is mainly divided into three parts: (1) Inverting the surface ground motion to the bedrock, calculate the surface response of the geological drilling points, and then obtain the regional seismic motion nephogram by Kriging interpolation method; (2) establishing the standardized and simplified models of regional bridges; (3) simulating the seismic response of regional bridges by nonlinear dynamic time-history analysis, than the structural damage states were quantitatively evaluated based on the smulation results. Taking 85 bridges in an area as an example, the earthquake disaster simulation was carried out. The results show that the method proposed in this study is efficient and can consider the cumulative damage of aftershocks to the structure, and can provide strong technical support for the selection of post-disaster rescue routes.
Experimental Study on Reinforced Single-column under Eccentric Load
Authors: Fu Wurong , Zhou Ruigen , Zhang Xinguo , Xia Ye
Published: August 2023

In recent years, accidents of overall lateral overturning of simply-supported and continuous girder bridges have occurred in the world. Since 2018, Shanghai has carried out overturning design verification and risk identification for such girder bridges. Based on the calculation results and the actual bridge inspection results, the paper proposes a reinforcement method for the bridges with single-column. An additional steel bent beam is connected to the column, and additional auxiliary bearings on the lateral sides of the original bearings are arranged. By this method the steel bent beam is connected to the original columns through studs, which can reduce the construction time and guarantee the behaviour between the single-column and the bent beam. A full-size test specimen was designed and tested to investigate the behaviour and capacity of the reinforced method.

Through the test results, load-displacement curved was obtained and cracks were observed and recorded. The joint between UHPC and the column cracked and was the unfavourable design section for the method.

This method can guarantee the force state of bridges under service time, and the anti-overturning capacity is increased by the additional steel bent beam and bearings under extreme loading conditions.

Мета статті – удосконалення рівня професійної діяльності тренерів із силового фітнесу за допомогою використання показників варіабельності серцевого ритму для розширення методів діагностики функціональ- ного стану спортсменів та оцінки адаптаційних реакцій на навантаження. Методи. Для досягнення поставленої мети залучено 40 нетренованих чоловіків 18–20 років і 20 тренованих юнаків, які займаються силовим фітнесом протягом трьох років. Сформовано три дослідні групи по 20 осіб у кожній. Представники контрольної та 1-ї основної груп (нетреновані) й представники 2-ї основної групи (треновані) застосували протягом трьох місяців дослідження різні режими силового навантаження. Для оцінки процесів вегетативної регуляції серцево- судинної системи використовували методи аналізу варіабельності серцевого ритму (ВСР). Результати. На початку досліджень у контрольній групі реакція серцево-судинної системи відображає найбільш знижений рівень резистентності до навантажень середньої інтенсивності й великого обсягу тренувальної роботи. Застосування навантажень великого обсягу роботи та низької інтенсивності підвищує параметри показника наднизькочастотного спектра коливань кардіоінтервалів з одночасним зниженням активності низько- й високо- частотного спектра в порівнянні з даними, установленими під час роботи в режимі високої інтенсивності та малого обсягу. Показники ВСР учасників усіх груп після трьох місяців тренувань свідчать, що процес довготривалих занять силовим фітнесом в умовах заданих режимів навантаження приводить до економізації функціонування серцево-судинної системи. У кінці програми дослідження в юнаків усіх трьох дослідних груп у стані спокою виявлено більш виражене превалювання наднизькочастотного спектра (VLF). Висновки. Поглиблене вивчення та практичне застосування методу варіабельності серцевого ритму в процесі діагностики адапта- ційних змін в організмі під час використання різних режимів навантаження дає змогу удосконалити рівень професійної діяльності тренерів із силового фітнесу.

Мета статті – дослідити особливості впливу використання різних режимів силового навантаження на показники складу тіла спортсменів у період спеціалізовано-базової підготовки в ММА. Методи. У дослідженні брали участь 75 спортсменів. Їх розділено на три однотипні за кількістю учасників групи. Представники обсте- жених групи використовували різні за обсягом, інтенсивністю енергозабезпечення навантаження. Використо- вуючи метод біоімпедансометрії, оцінювали зміну показників складу тіла спортсменів (жирову, безжирову, суху клітинну та активну масу тіла). Результати. Виявлено, що в спортсменів 1-ї групи, які використовували в процесі силової підготовки класичний для єдиноборств режим навантажень (Rа=0,53), виявлено найбільше серед обстеженого контингенту зниження рівня жирової маси (на 2,5 %). При цьому показники безжирової й активної маси тіла в спортсменів 1-ї групи практично не змінились. У спортсменів 3-ї групи в процесі застосування незвичайного за інтенсивністю та енергозабезпеченням для ММА режиму силового навантаження (Rа=0,72) на тлі зниження рівня жирової маси на 2,2 % спостерігаємо підвищення інших досліджуваних показ- ників. Так, у спортсменів 3-ї групи показник безжирової маси тіла підвищується на 4,2 % у порівнянні з вихід- ними даними. Відповідну позитивну тенденцію до зростання на 1,9 % виявлено під час контролю за динамікою показника активної маси тіла. У спортсменів 2-ї групи, які в процесі дослідження застосовували режим силового навантаження (Rа=0,65), притаманний переважно для занять бодібілдингом, виявлено лише підви- щення рівня безжирової маси тіла на 3,4 %. Інші контрольовані показники демонструють лише тенденцію до змін. Висновки. Використання на етапі спеціалізовано-базової підготовки в ММА режиму навантажень високої інтенсивності (Rа=0,72) в умовах креатинфосфокіназного механізму енергозабезпечення сприяє найбільш вираженим змінам показників складу тіла спортсменів.

In several developed countries such as the United States of America (USA), Japan, and the United Kingdom, Intellectual Property Rights (IPR) education has an important role in empowering IPR. The existence of HKI education also increases the growth of the creative economy. Therefore, the creative economy sector is growing rapidly and contributing significantly to Gross Domestic Product (GDP), labor absorption, and exports. However, it is different from the people in Indonesia who still lack understanding and awareness of IPR. On the one hand, IPR has moral and economic values that must be protected. This paper aims to examine the urgency of HKI as a compulsory subject in universities in Indonesia This type of research is legal research using a comparative approach. The data collection technique was carried out by means of a literature study. Data analysis techniques were carried out using normative juridical methods. The results of the study stated that HKI has an urgency as a compulsory subject in tertiary institutions due to several things, first, innovations and research results produced in tertiary institutions are HKI objects that must be protected. In addition to encouraging innovation, this is intended so that inventors and creators can have moral and economic values for their findings. Second, the prevalence of IPR violations in tertiary institutions is an indication of the importance of IPR Education as a general compulsory subject. Third, downstream research results. The main asset in downstream research results is intellectual property owned by creators and inventors. The results of higher education research are the values of originality, innovation, and uniqueness that require the protection of intellectual property. IPR education can be a medium to increase awareness of legal protection for a research result produced by academics.

O uso da planta de valores genéricos (PVG) para fins de tributação imobiliária é uma eficiente ferramenta que os municípios dispõem para formação da base de cálculo do imposto predial e territorial urbano (IPTU). Essa base de cálculo é obtida, em geral, por meio de processos de avaliação em massa de imóveis. Nesse processo, um desafio comum é encontrar um modelo capaz de tratar adequadamente os habituais efeitos espaciais. Para tanto, este estudo investiga a aplicação da regressão geograficamente ponderada (GWR) na avaliação em massa de imóveis urbanos, comparando seus resultados com os obtidos pela regressão clássica (OLS). O estudo contou com 118 dados de apartamentos dos bairros Trindade e Agronômica, em Florianópolis/SC, dos quais 100 foram utilizados para gerar os modelos e 18 para validá-los. Os valores preditos pelas modelagens foram utilizados de forma combinada com o interpolador de krigagem para gerar uma PVG representativa da área em estudo. Os resultados mostraram superioridade da modelagem GWR em todos os indicadores de qualidade e desempenho, com predições muito mais precisas, demonstrando ser essa uma alternativa viável para geração da base de cálculo do IPTU, possibilitando, assim, uma tributação mais justa e equânime, pilares basilares para que se alcance justiça fiscal.
Modelos mistos na engenharia de avaliações: possibilidades e aplicações
Authors: Droubi Luiz Fernando Palin , Zilli Carlos , Hochheim Norberto
Published: August 2023

Este trabalho visa a introdução aos modelos mistos ou hierárquicos, com foco para a aplicação na Engenharia de Avaliações. A modelagem de efeitos mistos pode ser bastante útil na Engenharia de Avaliações quando há presença de heterogeneidade amostral, especialmente no contexto da ocorrência de ausência de dados em número suficiente para uma determinada característica, situação em que a estimação por modelos mistos é mais eficiente. Além disto, com a modelagem hierárquica se abre um campo muito interessante para a análise do impacto da presença de amenidades sobre os valores dos imóveis, possivelmente até embasando a realização de investimentos em infraestrutura e/ou intervenções urbanas com fins de valorização dos imóveis, visando a recuperação das mais-valias. Finalmente, os modelos mistos possuem grande aplicação para a análise de dados em séries temporais ou em painel, o que indica um grande potencial de aplicação destes modelos para a confecção de índices de preços de imóveis.

Environmental PM2.5, Physical Activity Levels, and Aerobic Capacity, of Smokers and Non-Smokers
Authors: Mayank Shukla , Sakshi Bansal
Published: August 2023

Aerobic capacity of young men (19 years - 24 years) is high, but can be influenced by many factors like physical activity, smoking, and air pollution with environmental PM2.5. Objectives: (a) - to estimate the aerobic capacity in young men (smokers and non-smokers) living in areas with higher PM2.5 using Queen’s College Step Test (QCT). (b) - to find whether aerobic capacity is associated with the International Physical Activity Questionnaire (IPAQ)’ three classes, for smokers and non-smokers. Methods: In a cross-sectional study using criteria-based sampling a total of N = 60 smokers & non-smokers were included from the Delhi NCR region. IPAQ, Peak Expiratory Flow Rate (PEFR), Heart Rate, Systolic Blood Pressure, Diastolic Blood Pressure, and PM2.5 and PM10 levels were recorded. A comparison of smokers and non-smokers was performed using z test. Smokers and non-smokers were divided into three classes using physical activity levels and compared for aerobic capacity. The correlation of aerobic capacity with variables was seen using Pearson’s correlation coefficient. Multiple R was checked to study the model of cause and effect for aerobic capacity. Results: Significant difference is seen between smokers and non-smokers in the aerobic capacity (Mean ± SD smokers - 65.22 ± 8.73 ml/kg/min; Mean ± SD non-smokers 60.04 ± 7.7 ml/kg/min p - value = 0.00). For non-smokers, a low level of physical activity shows a strong correlation with aerobic capacity (r = 0.78; p = < 0.05). No correlation of aerobic capacity is seen with physical activity levels among smokers. Aerobic capacity shows a significant negative and moderate correlation with PM2.5 (r = -3.1; p = 0.016). The multiple R coefficient value for the model of cause and effect is 6.99 with a p - value of 0.0449 for this. Conclusion: Smoking affects aerobic capacity significantly for young men. High and moderate levels of outdoor physical activity do not increase aerobic capacity in areas with high PM2.5, whereas low levels show a positive correlation among non-smokers only.
