桥梁的抗震性能一直是需研究的主攻课题。阐述了桥梁延性抗震设计与减隔震抗震设计方法的基本原理,并介绍了几种新型减隔震装置的性能及优缺点。对一拟建的连续梁桥在顺桥向地震作用下分别采用延性抗震设计和减隔震抗震设计,对比了顺桥向结构关键部位的地震响应,总结了其适用范围和关键控制因素,为同类桥梁工程的抗震设计提供了一定的借鉴作用。
The seismic performance of bridges has always been the subject of research. The basic principles of the bridge design of ductile seismic design and seismic reduction design of seismically isolated bridges are expounded. The performance, advantages and disadvantages of several new seismic isolation devices are also introduced. The seismic response of a proposed continuous girder bridge to the key parts of the structure along the bridge was compared under ductile seismic design and seismically isolated design respectively under the action of the quasi-seismic response to the bridge. The applicable scope and key control factors were summarized as Seismic design of similar bridge project provides some reference.
