Dynamic Response for Collision Load between Over-Height Truck and Curved Beam Bridge

Abstract:

In recent years, ultra-urban road overpass vehicle impact beam incident after another. High beam impact of vehicles on the overpass bridge safety impact has become another important issue. High trucks at home and abroad on the curve of reinforced concrete beam bridge working effect of the impact is still insufficient. Based on high-precision linear dynamic finite element simulation analysis, research under the action of high vehicle collision, reinforced concrete curved girder Bridges of local damage effect and the overall distortion performance. The results showed that: high vehicles on the bridge superstructure imposed impact impulse and punching power led bridge superstructure is hitting zone produce local cracks. Damage caused by different impact velocity varied.
