Abstract:The present condition of China's seismic design of continuous girder bridges is discussed firstly,and seismic isolation design principle is recommended.The configuration and working mechanism of the double spherical aseismic bearing developed recently are introduced in detail and the seismic performance test results of the bearing are introduced and analyzed briefly.According to a seismic analysis of a continuous girder bridge with eleven spans,this kind of bearing is suitable for the seismic design of continuous girder bridges.
Keywords:double spherical aseismic bearing  continuous girder bridges  seismic isolation
