【摘要】 本文对钢筋混凝土高层结构进行了推覆分析研究,并编制了相应的推覆分析计算机程序。为了满足复杂体型高层结构的需要,提出了多种类型的单元,包括梁柱单元、单片墙单元、三垂直杆墙元和筒体墙单元,与试验结果对比分析表明这些模型具有很好的精度,并且能够搜索到结构反应的全过程,甚至结构的软化阶段。最后对一栋具有复杂体型的高层结构实际工程进行了推覆分析研究,为结构设计提供了实用的参考依据。更多还原

【Abstract】 In this paper, the study of pushover analysis and corresponding computer program for RC tall structures is carried out. Several kinds of elements in the program are considered to meet the need of tall buildings with complex structural type. These elements include beamcolumn element for beams and columns, single slice wall element and three vertical line element for walls, tubewall element for tubes. Calculation example for verifying the models indicates that the result obtained by this method is identical with a wellknown test result and the program can search for the whole process of structural response, induding the softening stage of the structure. Applying this pushover analysis method, the analysis of actual tall building with complex structural type are completed, and the result are put into practice for structural design of building.更多还原
