| 摘 要： | 基于纤维模型理论,利用PERFORM-3D软件实现了复杂超高层建筑结构的弹塑性时程分析并进行构件变形性能评估。针对PERFORM-3D建立高层结构模型的复杂性,开发了其前处理程序ETP,使之能够方便准确地建立弹塑性模型。分析表明,基于纤维模型的整体结构弹塑性分析法高效可行,不但宏观上可得到结构整体响应,而且微观上可得到构件的内力及变形和纤维的应力及应变。通过工程实例,得到整体结构响应、构件的变形及结构能量耗散情况,可用于研究按我国现行规范设计的超高层混凝土结构在罕遇地震作用下的非线性变形及受力特点。

| Abstract: | Elasto-plastic time-history analysis and component deformation performance evaluation of complex super high-rise building structure can be realized by the program PERFORM-3D based on the theory of fiber model.In order to reduce the complexity of tall building structure modeling,a pre-processing program named ETP was proposed.The research showed that elasto-plastic analysis of the whole structure based on fiber model was an efficient and successful method.In macro sense,the response of the whole structure ca... |
