Reliability Assessment of Simply Supported Beam Bridge Structural Performance Based on Load Tests

open access: yesAdvances 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

Assessment Method for Driving Risk of Heavy‐Duty Trucks at Interchange Ramps

open access: yesJournal of Advanced Transportation, Volume 2026, Issue 1, 2026.
The accident rate of interchange ramps based on investigated Chinese cases is approximately two times higher than that of mainline sections, where losses in human lives and economic costs caused by heavy‐duty truck (HDT) accidents are far greater than those of sedans. Nevertheless, existing risk assessments overlook the coupled effects of human–vehicle–
