钢框架开洞钢板剪力墙滞回性能分析

摘要

A single span two layers of steel frame-open hole plate shear wall structure finite element model was established by finite element software ANSYS, the hysteretic performance of the model was analyzed. The hysteretic curves of different high thickness, different open hole size, different the vertical load was obtained. The results show that: along with the increase of the thickness of the steel plate handled, structure of the energy dissipation capacity increase; along with the increase of the steel plate width, structure capability of energy consumption gradually reduced; when the vertical load is small, different vertical load on the structure of the hysteretic performance influence is very small.%利用有限元软件ANSYS建立了单跨两层钢框架-开洞钢板剪力墙结构的有限元模型,对模型进行滞回性能分析,获得不同高厚比、不同开洞大小、不同竖向荷载下的滞回曲线,结果表明:随着钢板厚度的增加,结构的耗能能力逐渐提高；随着钢板洞口宽度的增加,结构的耗能能力逐渐降低；当竖向荷载较小时,不同竖向荷载对结构的滞回性能影响很小.
