摘要
桥梁抗震是近年来一直比较关注的问题,如何能保证主要桥梁在地震后不至于完全垮塌或通过维修即可恢复使用是桥梁抗震的主要研究方向和目标。结合汶川地震震害分析,利用桥梁有限元分析软件Midas,重点研究了桥梁桥墩的抗震特性,并提出了桥墩合理的抗震措施和桥墩塑性铰设置位置。
The bridge seismic resistance is an issue that is always paid attention to in recent years. How toguarantee the recovery and use of bridge after the earthquake due to the reason that it did not collapse totally orrepair is the main research direction and objective of bridge seismic resistance. In combination with the analysis onthe damage of Wenchuan earthquake, the research on the seismic character of the bridge pier is made emphaticallyby utilizing the finite element analysis software Midas, and the reasonable seismic fortification measures for bridgepier and the set position of plastic hinge of bridge pier are put forward.
