| 摘 要： | 应用大型有限元分析软件AN SY S,对武汉长江二桥的主要构件梁、索、塔、普通钢筋和预应力钢筋分别采用不同的单元进行了有限元模拟.考虑了斜拉索自重作用下垂度引起的几何非线性效应、梁柱效应和结构大位移效应等3种非线性效应的影响,计算了大桥在静载作用下的应力、应变和挠度.计算的结果与成桥后荷载试验的结果相符,表明采用的方法是可行的.

| Abstract: | A finite element model of a large cable-stayed pre-stress steel-reinforced concrete bridge,which is named Wuhan Second Yangtze River Bridge located in Wuhan is created.The model is analyzed by ANSYS software.The model includes 4 types of elements such as Solid45 element represents reinforced concrete beam,Solid65 element represents the pre-stress steel-reinforced concrete towers,Link10 element represents high stress cables and Link8 element represents pre-stress rebar.The bridge's static nonlinear behavior is analyzed,which includes the cable sag effect,the beam-column effect and the large displacement effect.The vertical displacement is computed.The results of finite element analysis show the model is correct and the results coincide with the tested results well. |
