摘要
该文结合某人行天桥的工程实例,利用Ansys软件采用梁单元、桁架单元、板单元建立分析模型,分析中考虑了钢筋混凝土柱的弹塑性性能,得到其在地震作用下的时程响应,为过街天桥的抗震分析得到有益结论。
According to the engineering case of a pedestrian overpass,Ansys software is utilized to set up the analysis model by the beam element,truss element and shell element,and the elasticoplasticity perfromance of the steel reinforced concrete columns is considered in the analysis so as to get the time-history response subjected to earthquakes.And the useful conclusion is got for the anti-earthquake analysis of pedestrian overpass.
