基于ANSYS有限元仿真的混凝土连续梁桥地震响应分析

Seismic Response Analysis of Concrete Continuous Beam Bridge Based on ANSYS Finite Element Simulation

桥梁结构的抗震性能研究是我国公路交通建设面临的重大课题,而桥梁地震响应仿真分析有助于提高设计质量,保障桥梁的抗震能力.本文以三跨变截面混凝土连续梁桥为例,采用ANSYS有限元分析软件针对天津地震波作用下连续梁桥的地震响应进行仿真分析.研究结果表明:该连续梁桥在天津地震波作用下,没有出现较大位移变形,结构抗震能力符合规范要求.

The research on seismic performance of bridge structure is a major task to our country's highway traffic construction.The bridge seismic response simulation analysis helps to improve the design quality and ensure the seismic capacity of the bridge.Taking three-span continuous girder bridge with variable cross-section as an example,the ANSYS finite element analysis software was used to simulate the seismic response of continuous girder bridge under the action of Tianjin earthquake.The results showed that the continuous beam bridge had no larger displacement and deformation under the action of Tianjin seismic wave,and the seismic capacity of the structure met the requirements of the standard.
