- Abstract:
-
Most of the old rigid arch bridges in service are seriously damaged, taking a canal bridge on the 327th line in Shandong Province as an example. Combined with the structural characteristics of steel frame arch bridges. The static and dynamic mechanical properties were analyzed by the space finite element method, and the force characteristics and damage failure mechanism were discussed. It is revealed that the old rigid arch bridge designed according to the old code has insufficient bearing capacity and is in urgent need of reinforcement and maintenance. The analysis results provide a basis for its performance evaluation, and provide reliable technical data for the continued safe use, maintenance, reinforcement, reconstruction or restriction of bridge traffic, and the results can be used for the analysis of other similar bridges.
