| 摘 要： | 以一典型桥墩结构为例,采用有限元程序sap2000建立桥墩结构空间有限元计算模型,采用动态时程分析法对不同墩高桥墩结构进行地震反应分析,着重讨论不同地震动输入下不同高度桥墩的底部内力以及墩顶变形的地震反应变化规律,分析结果为同类桥梁结构的抗震设计提供理论依据。

| Abstract: | Based on an engineering design case of single-pier structure, the three-dimensional analysis model was developed using the FEA software sap2000. The dynamic characteristic and seismic response of single-pier structure was discussed with the time history method. The regularity of seismic response of the single-pier with different-height under different earthquakes was studied in detail. The results from the present study may serve as a reference base for seismic design of the same bridge structure. |
