【摘要】 在对薄钢板剪力墙结构试验研究的基础上,利用ADINA分析程序建立了非线性有限元滞回分析模型,具体分析了反复加载下薄钢板剪力墙构件的受力破坏特征及抗震性能。从理论分析角度,探讨了在地震区使用薄钢板剪力墙结构的可行性。模型的分析计算显示,对于钢筋混凝土框架结构,当设计的钢板长细比适宜时,在框架内填充钢板组成的薄钢板剪力墙,可显著提高结构的刚度、承载力,同时也具有较好的延性及耗能性能,其计算所得结果与试验相一致。更多还原

【Abstract】 Based on experiment results , a ADINA nonlinear finite element model was established in this paper, the load-carrying capacity and seismic behavour under cyclic load were analyzed. The results of analysis show that,with proper panel slenderness ratio,the effective use of thin steel-plate shear walls to resist seismic forces is possible. Addition of an unstiffened thin steel plate to a frame gives the system a great increase in stiffness, load-carrying capacity, ductility, energy dissipation and in good agreement with those of experiments.更多还原
