| 摘 要： | 探讨了基于两水准设防的城市高架桥的合理抗震设防标准与相应的结构性能目标.选取两座典型的城市高架桥结构,包括一座正线桥和一座匝道桥,分别采用延性抗震体系和减、隔震体系进行结构抗震设计.对比了不同结构抗震体系所对应的结构在各水准地震作用下具体抗震性能表现,结果表明减、隔震体系具有更优的抗震性能.在此基础上,进一步从经济性的...

| Abstract: | The rational multilevel seismic fortification criterion and the corresponding performance objectives were discussed for urban expressway viaducts.Two typical continuous girder viaducts,a mainline bridge and a ramp bridge,were analyzed in this study.For each bridge,a traditional ductile earthquake resisting system and an isolation earthquake resisting system were considered.The detail structural seismic performances corresponding to the two different earthquake resisting systems were compared at each design ... |
