摘要
Disclosed is a seismic load transmitting system based on impact mechanism for a multi-span continuous bridge. There are impact assemblies connected to a superstructure of the bridge for colliding with movable support piers according to a longitudinal displacement of the superstructure of the bridge caused by a seismic load. The seismic load is transmitted from the superstructure of the bridge to the movable support piers. These are impact receiving assemblies installed in the movable support piers for receiving an impact force generated when the movable support piers become collided with the impact assemblies and transmitting the seismic load transferred from the superstructure of the bridge through the impact assemblies to the movable support piers. The seismic load generated in the superstructure of the bridge is transmitted not only to the fixed support piers but also to the moving support piers due to the collision between the impact assemblies and the impact receiving assemblies. The contact plate of the impact receiving assembly has a curved surface of a predetermined curvature.
