Research on Bearing Capacity of Simply Supported Skew Bridge Based on Load Test

The purpose of this paper is to use static and dynamic load tests to evaluate the mechanical performance of a simply supported skew slab bridge and to evaluate its actual bearing capacity. Firstly, the Midas Civil software is used for theoretical simulation, and secondly, the deflection, strain, and...
