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 evaluate the mechanical performance a simply supported skew slab bridge its actual bearing capacity. Firstly, Midas Civil software used for theoretical simulation, secondly, deflection, strain, response key section are studied through tests. Finally, measured values compared analyzed. results show that: under load, relative residual deflection strain measuring point structure between -13.8%～-0.4% -16.7%～1.8% respectively; Under first-order vertical natural frequency test 7.813, damping ratio 0.0316, indicating that in an elastic working state stiffness capacity can meet requirements current code.
