基于ANSYS的连续刚构桥地震响应分析

Seismic response analysis of continuous rigid frame bridge based on ANSYS

以某连续刚构桥为工程背景,基于ANSYS建立全桥有限元模型,由规范反应谱生成人工地震波,分别采用直接加速度法与大质量法对结构进行地震反应时程分析,分析方法与研究结果对实际工程有一定借鉴作用。

Based on the engineering background of a continuous rigid frame bridge,the finite element model of the whole bridge is established based on ANSYS,and artificial seismic waves are generated from the standardized response spectrum.The seismic response time history of the structure is analyzed by direct acceleration method and large mass method respectively.The analysis method and research results can be used for reference in practical engineering.
