某城市桥梁弹塑性地震性能分析

Analysis on Elastoplastic Seismic Performance of an Urban Bridge

结合工程实例,建立了空间有限元仿真模型,对其进行了相应的时程分析,对固结墩在罕遇地震作用下的抗震性能进行分析。结果表明,该处桥墩在罕遇地震作用下塑性变形满足规范设计要求,分析结果可为该桥的设计提供指导。

According to the engineering cases, the space finite element simulation model is established to carry out the relevant time history analysis and analyze the seismic performance of consolidation pier under the rare earthquake. The result shows that the plastic deformation of this pier satisfies the norm design requirement under the rare earthquake. The analysis result can be referred for the design of this bridge.
