摘要

运用ABAQUS有限元软件建立装配式钢板剪力墙自复位平面钢框架模型进行变参数分析,研究钢材等级、板件厚度、宽度、板件开缝情况对结构动力性能的影响,分析结果表明:提高钢材强度等级能够增加结构抗侧刚度,控制层间位移角;增加钢板剪力墙板件厚度能够使结构位移响应减小,耗能能力增强;增加板件宽度使结构最大开口转角和最大残余转角增加,对结构整体耗能能力以及抗侧刚度影响不大;开缝钢板剪力墙相较于不开缝钢板剪力墙虽对结构抗侧刚度提高较小,但耗能能力更强,能够保护框架主体结构,有效减缓柱脚塑性发展,减少结构塑性损伤.
        Finite element software ABAQUS was utilized to establish the variable parameter analysis of the prefabricated and self-centering steel frame with steel shear walls. The influence of the steel grade,the thickness of the plate,the width and slit or not on the dynamic performance of the structure are studed by using ABAQUS. The results show that the improvement of the steel strength grade can increase the lateral stiffness of the structure and control interlayer displacement. Increasing the thickness of the steel plate shear wall panel can reduce the displacement response of the structure and increase the energy dissipation capacity. Raising the width of the plate parts can increase the maximum opening angle and the maximum residual angle of the structure,and have little effect on the overall energy dissipation capacity and the lateral stiffness of the structure. The lateral stiffness of the slit steel plate shear wall compared to the steel plate shear wall is of a little increasement. However,the energy dissipation capacity is stronger,and the slit steel plate shear wall can protect the main structure of the frame,effectively reduce theelastoplastic development of the column base,and reduce the plastic damage of the structure.
