Reliability Assessment of Simply Supported Beam Bridge Structural Performance Based on Load Tests
Currently, bridge load tests use the verification coefficient to evaluate the structural performance of bridges in China, but this method is unsuitable. This paper presents a method that utilizes reliability to compare the actual bridge structural performance with the designed performance. Reliability functions for strain and deflection in load testing

Study on Mechanical Behavior of Longitudinal Wet Joints of Prefabricated Assembled Beam
This study investigates the impact of various interface construction techniques on the bending strength of longitudinal wet joints in bridge superstructures through experimentation. A functional relationship between measured bending strength and theoretical shear strength values is established by finite element simulation.

Experimental Study on Reasonable Steam Curing Scheme of Prefabrication Box Girder
The assembly‐line production mode was adopted to meet the production demands of prefabricated box girders for the Haiyan line. The steam curing method was introduced to accelerate concrete strength development, allowing the prestressing tension requirements of the box girders to be met quickly.

The construction of cross‐sea bridges is increasingly essential in modern infrastructure, but it poses significant challenges due to complex environmental conditions such as strong tidal forces, waves, and ocean currents. These factors can lead to scouring of pile foundations, severely affecting the stability and safety of the bridge structure.

Safety Performance Evaluation of a Novel Portable Concrete Barrier Based on Vehicle Impact Test
Portable concrete barriers (PCBs) are modular structures widely used to separate traffic lanes from construction zones. However, these barriers often exhibit insufficient structural safety to effectively block intruding vehicles, leading to severe casualties.

Structural Behaviour Of Distressed And Strengthened Post-Tensioned Box Girder Beams [PDF]
Box girder prestressed concrete beams are used widely in bridge construction due to its efficient structural response under flexural as well as torsional loading. Prestressing can be either internally or externally applied to a beam.
