| 摘 要： | 首先给出地震作用下单墩横桥向分析模型,并阐述在地震作用下单墩横桥向分析过程中,挡块间隙与桥墩—挡块—支座各部分之间的关系;通过运用非线性时程方法对采用弹性挡块、橡胶缓冲挡块和弹塑性挡块3种不同类型挡块时不同挡块间隙对桥墩横桥向抗震性能的影响进行了分析比较。

| Abstract: | The model is given to analyze the seismic performance of single bridge pier in transverse direction.It demonstrates the relationship between block gap and bridge pier-block-support in the analysis of the seismic performance of single bridge pier in transverse direction.After then,it makes analysis and comparison of the block gap influence on seismic performance of pier in transverse direction when adoption of three different blocks i.e.elastic block,rubber buffer block,and elastic-plastic block by nonlinear time tracing method. |
