摘要
简述了带缝软钢阻尼墙的特点和受力机理,通过ABAQUS软件对5种软钢阻尼墙进行了非线性分析,得出了各自的滞回曲线,由此进一步对比分析了其耗能能力和滞回特性。结果表明,带竖缝的软钢阻尼墙承受反复荷载时,改变了原有钢板依靠剪切变形的耗能方式,主要以缝间壁柱的弯曲变形进行耗能,具有良好的延性和滞回性能。试件ZNQ-2～试件ZNQ-5中,以ZNQ-4型软钢阻尼墙的耗能性能最佳。本文分析结果为软钢阻尼墙更深入的研究提供了基础资料。
In this paper, the features and stress mechanis of mild steel damping wall are briefly described. The five kinds of mild steel damping walls are analyzed with ABAQUS software. It is concluded that the hysteresis curve and the energy dissipation capacity and hysteresis characteristics. The results show that the consumption mode is changed from shear deformation of steel to mainly bending deformation by columns between slits when mild steel damping wall with slits are under repeated load. It has the good ductility and hysteretic performance. Among the five test pieces from ZNQ-2 to ZNQ-5 , the dissipation characteristic of ZNQ-4 mild steel damping wall is the best. The results provides basic information for the more in-depth research of mild steel damping wall.
