钢混框架薄钢板剪力墙多层结构抗震

Hystereisis Analysis of Multi-storey Thin Steel-plate Shear Wall with finite Element Method

在对薄钢板剪力墙单层结构理论和试验研究的基础上,利用ADINA分析程序建立了非线性有限元多层结构滞回分析模型,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,探讨在地震区使用薄钢板剪力墙多层结构的可行性。模型的分析计算显示,对于钢筋混凝土框架多层结构,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,对工程应用具有重要的参考价值。

Based on single storey structure theoretical and experiment results, a ADINA nonlinear finite element multi-storey model was established in this paper, and the load-carrying capacity and seismic behavior under cyclic load were expictly analyzed. The results of the analysis show that, with proper panel slenderness ratio and effective use of thin steel-plate shear walls to resist seismic forces is possible. An unstiffened thiu steel plate to a frame gives the system a great increase in stiffness,load-carrying capacity, ductility, energy dissipation and has important preference value in practical engineering.
