薄钢板剪力墙简化分析模型

SIMPLIFIED MODEL OF THIN-WALLED STEEL PLATE SHEAR WALLS

  • 摘要: 在结构体系中钢板剪力墙作为抗侧力构件能充分发挥其承载力高、延性好、耗能能力强等优点。采用ANSYS有限元软件分析了薄钢板剪力墙在滞回荷载作用下的力学性能,并用试验结果验证了有限元分析的正确性。在此基础上分析了高厚比为500的钢板剪力墙滞回性能,探讨了薄钢板剪力墙的工作机理与受力模型。基于已有的等效拉杆模型,并针对其不足提出了改进型“混合杆系”模型,能更精确模拟其在滞回荷载作用下的承载力和耗能能力。

     

    Abstract: As a kind of new lateral load resisting member, steel plate shear wall (SPSWs) has some advanced points, such as high loading-carrying capacity, good ductility and excellent energy dissipation capacity. This paper presents the finite elment analysis of thin-walled SPSWs under a cyclic load, whose results are validated by comparing with experimental results. Based on the finite element model, the hysteretic behavior of SPSWs with height-to-thickness ratio of 500 is analyzed. Then a simplified combined strip model is proposed, which is suitable for the analysis of SPSWs in structural analysis.
