Parameter Optimum of Lead-rubber Bearings (LRB) in the Long-span cable-stayed Bridges

ZHANG Kai,GUO Wen-hua(School of Civil Engineering,Hunan City University,Yiyang 413000,Hunan,China)  
Reducing vibration by lead-rubber bearings was proposed in long-span cable-stayed bridge.Spatial finite element models of a long-span cable-stayed bridge and LRBs were established respectively.Seismic responses of the bridge were calculated through time-history analysis;parameter optimum of LRBs was carried out by orthogonal design.The results indicated that LRBs with optimization design could effectively reduce seismic response of the cable-stayed bridge.
