FP B－LRB联合隔震性能研究
Study on the performance of FPB-LRB co mbined isolation
摘要
Abstract
FPB support and LRB support are bearing more popularity at present,of which each has its unique advantages and disadvantages.With the aid of a combined 3 span prestressed concrete box girder bridge,the combined effects of FPB-LRB were discussed.The nonlinear process analysis method was used to analyze the in-fluence of different LRB bearings layout position of FPB-LRB isolated bridges,and only laid FPB supports were compared.The results show that the FPB-LRB isolates bridges with FPB isolated bridges with better isolation performance,proper layout of LRB support position can further improve the FPB-LRB isolation of bridge damp-ing ratio.关键词
