Flexural Behavior of a 30-Meter Full-Scale Simply Supported Prestressed Concrete Box Girder
Applied Sciences, 2020 Compared with scaled-model testing, full-scale destructive testing is more reliable since the test has no size effect and can truly record the mechanical performance of the structure.

Theory and Field to Determine the Construction of Bridge and Tunnel Linked Segment
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Bridge–tunnel linked sections characterized by ultra‐small clear distances and steep slopes pose significant construction risks due to strong spatial constraints and complex mechanical interactions between adjacent underground structures. In such conditions, excavation method selection becomes a critical factor governing construction safety and ...

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.This study focuses on simply supported railway box girder bridges with pre‐existing cracks under high‐speed train loading. A vehicle–bridge coupled vibration model is established, and three‐dimensional dynamic stress intensity factors at the crack tip under various loading conditions are obtained using the interaction integral method.

The Effect and Mechanical Mechanism of Intermediate Diaphragms in Prefabricated T‐Beam Bridges
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Current bridge design codes stipulate that prefabricated T‐beam bridges must include intermediate diaphragms, with spacing not exceeding 10 m. However, the construction of these diaphragms entails extensive overhead work, elevated safety risks, and significant challenges in quality control.

Reliability Assessment of Simply Supported Beam Bridge Structural Performance Based on Load Tests
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.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
