Analysis and Evaluation of Bearing Capacity of Steel-Concrete Composite Girder Bridge Based on Load Test Detection
Under the action of long-term load and environment,bridge structures have safety risks such as material performance degradation,structural instability,and reduced load-bearing capacity.This paper takes a steel-con-crete composite girder bridge as an example and uses a variety of detection and test methods to detect the appear-ance,material,dead load variation,dynamic characteristics,and static characteristics of the bridge.It focuses on the relevant methods used in the load test process and precautions.The test results of the bridge's fundamental fre-quency,main section stress,strain,and residual deformation truly reflect the structural characteristics of the bridge,provide strong support for the objective evaluation of the actual working performance of the bridge,and provide a useful reference for the implementation of similar projects.
