两层双柱岛式地铁车站结构水平向非线性地震反应分析
|
摘要
采用在ABAQUS软件上开发实现的土体动非线性黏弹性模型模拟土的动力非线性,采用J.Lee提出的混凝土动力塑性损伤模型模拟隧道管片混凝土在循环荷载下的非线性特性,利用大型商业有限元软件ABAQUS对南京地区两层双柱岛式地铁车站结构的水平向非线性地震反应特性进行了数值模拟。数值分析表明:地铁车站在侧墙和顶板、中板和底板的连接处发生动应力集中现象,其中尤其是在中板和侧墙的连接部位动应力反应尤为严重;其次是上层中柱顶端和下层中柱底端出现很强的动拉压应力;在中板和中柱的连接部位也出现很强的动应力集中现象。这些计算结果表明,两层双柱岛式地铁车站结构的中柱和中板是地震反应最不利部位,这应引起地铁车站结构设计人员的重视。
The nonlinear earthquake response of two-layer double-column subway station built in Nanjing City is analyzed by ABAQUS software.The nonlinear characteristics of soil under cyclic loading is simulated by a dynamic nonlinear constitutive model proposed by authors which is implemented in ABAQUS software.The nonlinear characteristics of concrete under cyclic loading is simulated by plastic-damage constitutive model proposed by Jeeho Lee.The results indicate that dynamic stress concentrates in the junctions of side walls and level boards,and level boards and columns.Especially,dynamic stress concentrates severely in the junction of side wall and medial board,and columns and top or bottom boards.The junctions of subway station should be reinforced.
