【摘要】 采用有限元分析软件SAP2000对钢框架-支撑结构体系和钢框架-带缝钢板剪力墙体系进行了计算分析。通过研究比较两种结构体系的塑性铰发展情况,提出一种新型的混合式结构体系(即下部采用带缝钢板剪力墙,上部采用支撑),并对其破坏模式进行了研究。另外,借助于VC语言,编制出了求解带缝钢板剪力墙抗侧刚度的程序,可以通过调节钢板剪力墙的开缝程度来改变加强层的整体抗侧刚度,有利于该类结构体系在设计工作中的推广。更多还原

【Abstract】 Steel frame-support system and steel frame-steel plate shear wall system were analysis using finite element analysis software SAP2000.By comparing the plastic hinge’s development of the two structure systems,a novel hybrid structure system(lower part with steel plate shear wall,the upper part with support) was put forward,and its failure mode was studied.In addition,the program of solving steel plate shear wall’s lateral stiffness was worked out by means of VC language.The overall lateral stiffness of enhancement layer was changed by adjusting the slotted level of steel plate shear wall,which benefits the promotion of such structure systems in the design.更多还原
