Failure Analysis on a Curved Girder Bridge Collapse under Eccentric Heavy Vehicles Using Explicit Finite Element Method: Case Study

In recent years, several similar bridge overturning and collapse accidents have occurred in China. All of them occurred on bridges with continuous monolithic box girders and single-column piers that were eccentrically overloaded by heavy vehicles. In this study, an explicit nonlinear dynamic finite element method is used to analyze an accident occurred on an expressway exit ramp bridge. The entire overturning and collapse process is simulated....
