首先,对薄钢板剪力墙简化分析模型进行研究,采用通用有限元软件Abaqus建立薄钢板剪力墙Shell单元模型以及采用SAP2000建立等效拉杆简化分析模型,对比两种模型在静力荷载下的力学性能,从而得到等效拉杆模型杆元根数的合理范围。其次,修正了薄钢板剪力墙简化分析模型中杆元面积计算公式,更好地模拟薄钢板剪力墙的初始抗侧刚度。最后,对比等效双向拉杆模型与Shell单元模型两种模型的滞回性能,结果表明:采用SAP2000建立的等效双向拉杆简化分析模型能够较好地模拟出薄钢板剪力墙的滞回性能。
Firstly, the simplified analysis model of the shear wall of the thin steel plate is studied, the shell element model of the thin steel plate shear wall is established by using the general finite element software Abaqus, and the simplified analytical model of the equivalent rod is established by SAP2000. Comparing the two models under the static load Mechanical properties, so as to get a reasonable range of equivalent number of rod model rod element. Secondly, the calculation formula of the rod element area in the simplified analysis model of the thin steel plate shear wall is revised, and the initial lateral stiffness of the thin steel plate shear wall is simulated better. Finally, the hysteretic performance of the two models of the equivalent two-way tie rod model and the Shell element model is compared. The results show that the hysteretic behavior of the thin-walled shear wall can be well simulated by using the equivalent two-way tie rod simplified analysis model established by SAP2000.
