%X FPB支座和LRB支座都是目前较受欢迎的减隔震支座,各自有其独特的优缺点。借助一联3跨预应力混凝土箱梁桥,探讨FPB-LRB的联合作用。采用非线性时程分析方法,分析不同LRB支座布设位置对FPB-LRB隔震桥梁的影响,并与只布设FPB支座进行比较。研究结果表明:FPB-LRB隔震桥梁较FPB隔震桥梁具有较优的隔震性能,恰当的布设LRB支座位置,可以进一步提高FPB-LRB隔震桥梁减震率。<br>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 influence 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 damping ratio
