基于Push-over算法的钢筋混凝土结构的静力弹塑性分析
|
摘要
介绍了弹塑性变形分析Push-over算法的基本原理,以某钢筋混凝土高层双塔连体结构为算例,用EPSA软件对其进行7度、8度、9度的多遇及罕遇地震下的静力弹塑性分析(Push-over),并得出力—变形曲线,判断整个结构的受力性能和延性好坏。
This paper introduces the basic theory of the Push-over algorithm of elasto-plastic analysis, and by using the EPSA software(Push-over)and taking the high-rise conjoined twin-tower structures as an example, makes the static elasto-plasticity analysis on the reinforced concrete structures under frequently and seldom occurred at earthquake intensity of 7, 8 and 9 degrees, obtains the curve of force-deformation, and judges the load bearing capacity and the ductility of the whole structure.
