A powerful earthquake occurred in Maduo, Qinghai Province, China, on May 22, 2021. Bridges at the earthquake-stricken area were damaged or even collapsed. Post-earthquake field investigations of damaged bridges were conducted by the authors during May 28-30, 2021. This is a reconnaissance report on the damage to two typical girder bridges near the epicenter as well as possible damage mechanisms. It is found that the velocity pulse effect of near-fault ground motions could trigger excessive longitudinal displacements and severe pounding of superstructures of long multi-span girder bridges. Abutments could effectively reduce longitudinal seismic damage of short girder bridges through providing sufficient translational restraints.

Terrorist attacks have nowadays become an important issue for the structural design of constructions such as bridges. Indeed, during the last decades, the increase in the number of terrorist attacks has resulted in the loss of many human lives and socio-economic impact on our society. The aims of this research consist in a series of preliminary analyses in view of a study of the effects of an explosion on a long-span suspension bridge. As a suspension bridge was considered the project of the bridge over the Strait of Messina, having as main span of 3300 meters. The structure was modeled using ABAQUS/Explicit software using beams-type 3D finite element modeling. The objectives of the research are double. The first one is the study of the pressures generated by an explosive charge to model the phenomenon during numerical simulations while, the second objective, is to test different discretizations to have a reliable numerical response.

Near Samtse Dzongkhag in Bhutan, the country terrain is flat and hence the river ‘Dhamdum chu’ is very wide and remains dry during most of the time of the year. But during monsoon, rain water with melted ice from mountain, it becomes mighty. The bridge proposed over Dhamdum chu connecting the community residence to Samtse Industrial Park is a multiple span concrete bridge supported by solid concrete piers placed on open foundation. A very large span bridge was possible but not considered practical from the view point of economy and social aspect.This paper represents the output of non-linear analysis carried out during design of the bridge to ensure safety of the bridge Piers against damage by impact from flowing rock if any. Rock impact simulation of the bridge pier is done using Finite Element Code[1]. Continuous Surface Cap Model (CSCM) of concrete model is used to identify the possible damage of Pier concrete. Plastic kinematic model of steel is used to represent the reinforcing steel. Two-way automatic surface to surface contact algorithm is employed between the rock and the static Pier.

The ShiZiYang suspension bridge in the GuangDong province in China will when constructed have a world record main span of 2180 m and carry an impressive 2 x 8 lanes of traffic on the two levels truss girder.Due to its size, ShiZiYang bridge requires extensive main cable area with diameter nearly 1.5 m representing the largest main cable ever constructed. An option of dual main cables can be considered with smaller main cables including simpler compaction. However the construction time is extended, all adjacent structures such as saddles, anchorages and cable clamps become significantly more complex and the separate cables behave as independent members.The paper discusses the main key challenges regarding design and construction of large main cables with diameter above 1m and alternatively dual main cables.

Over recent years there has been considerable development in bridge engineering. Thirty-two bridge projects have received IABSE Outstanding Structure Awards during the past two decades in recognition of the most remarkable, innovative, creative, or otherwise stimulating structures. Several creative structural forms have been created such as two twin-box girder suspension bridges, three spatial main cable suspension bridges, six multi-main-span cable-supported bridges and one cable-stayed and suspension hybrid bridge. Various innovative material combinations have been developed and used in two steel truss and PC flange composite girder bridges, one butterfly web extradosed bridge, one multiple material strength bridge and one long-life concrete cable-stayed bridge. Some remarkable functional technologies have been invented for two remarkable movable bridges, two innovative cable-stayed bridges, two extreme seismic function cable-supported bridges and two environmental coordination bridges. Many stimulating bridge projects have been awarded as Winners or Finalists including three extradosed bridges, four arch bridges, two cable-stayed bridges and four sea-crossing bridges. The innovation and creation of recent bridge engineering has been recognised by IABSE Outstanding Structure Award reflecting the creative structural forms, the innovative material combinations, the remarkable functional technologies and the stimulating bridge projects.

This paper investigated the seismic performance of steel frames under earthquake motion. Two- story steel frames were designed based on a code-design method for a medium and high-risk seismic zone. The frame's nonlinear static and dynamic analyses have been performed using OpenSees software and sap2000. We consider diverse configurations, concentrated plasticity, and fiber-model were employed. The results obtained in the analytical study concluded that the user design method was reasonable and the mean maximum drift of the frames under the ground motion sets was in an acceptable range.

The study on the risk of ship-bridge collision has always been a significant subject in academic research. However, the study of ship-bridge collision risk is rarely mentioned from the perspective of the bridge life-cycle. This paper proposes the concept of "bridge-ship common safety" based on the synergetic theory and constructs a high-level cooperative platform to solve the problem of bridge-ship collision. It was given in this article by analyzing the interaction relationship among subsystems of environment, ship, and bridge. In this paper, it proposed the analysis method of the ship-bridge collision risk based on synergetic theory with order parameters, including ship-bridge collision probability and collapse probability of bridge. Finally, the Lanjiang Xiangnv Bridge project as the case study is demonstrated. The risk of bridges is evaluated by utilizing order parameters and synergetic degrees. The result shows that the model can reflect the risk of ship-bridge collision properly, which achieves great scientific significance and academic value for enriching the theory in bridge-ship collision avoidance and implementing the concept of " bridge-ship common safety ".

The main bridge of Nanjing Jiangxinzhou Yangtze River Bridge is in the form of a cable-stayed bridge with three towers and two main spans, with a total length of 1796m and a main span of 600m. The towers and main beams are all composite structures, which is the first all-steel-concrete composite cable-stayed bridge in the world. The bridge originally develops the steel shell-concrete composite tower, investigates coarse aggregate reactive powder concrete (CA-RPC), and applies it to the main girder to form a lightweight and high-performance beam. Numerous technologies have been achieved in new materials, new structures, new processes, and many other aspects. The unique structural concept has significantly increased the factory manufacturing speed, which not only reduces the work and labour cost 25% but also reduces the amount and loss of materials during construction, which has made contributions to the development of cable-stayed bridges.

Bridge influence surface (BIS), which reflects the relationship between the bridge response and the unit load moving on the bridge, has been commonly used in bridge weigh-in-motion, bridge damage detection, etc. Generally, the BIS can be obtained by interpolating bridge influence lines (BILs) at different lateral positions. In field tests, the BILs are usually extracted from the bridge response induced by a moving calibration vehicle with known axle loads. However, when taking the axle loads of the calibration vehicle into calculation, the impacts of the transverse distance between coaxial wheels and the unbalance of the coaxial wheel loads are ignored. Hence, errors may be brought to the calculated BIL and then propagated to the BIS. To remove these impacts, a new BIS calculation method, which takes the load of each wheel rather than each axle into calculation, is proposed in this research. Numerical simulation shows that the BIS can be successfully estimated by this method.

This paper presented a three-dimensional (3D) numerical model to explore the shear behavior of bolt connections embedded in steel-lightweight aggregate concrete composite beams (SLACCBs) by utilizing the ABAQUS software. Nonlinear geometric effects and material nonlinearities were considered in the finite element (FE) modelling. The accuracy and reliability of the FE modelling were validated against the push-off tests initially. Subsequently, the basic shear properties of the bolted connection embedded in SLACCBs were studied and compared with that of the bolted connection embedded in the normal concrete (NC) slab by applying the verified FE modelling. Meanwhile, the effects of the concrete strength, concrete density, bolt diameter, and bolt tensile strength on the shear behaviour of bolt connection embedded in SLACCBs were also investigated by extensive parametric studies.
