摘要:

推导了带缝钢板剪力墙弹性抗侧刚度的理论计算公式,利用有限元软件分析了竖缝、纵向边缘加劲、边界约束、钢框架梁大小等因素对弹性抗侧刚度的影响。通过对比计算结果与试验数据,得到了弹性抗侧刚度的修正计算公式; 在此基础上,提出了简单实用的带缝钢板剪力墙的弹性简化计算模型,并通过有限元分析对其正确性进行了验证。结果表明:柱状部抗弯刚度是决定弹性抗侧刚度的关键因素; 弹性抗侧刚度修正计算公式以及弹性简化计算模型具有较高的精度。

Abstract:

Theoretical calculating formula of elastic lateral stiffness of steel plate shear wall with slits(SPWS)was derived. The effects of vertical slits, longitudinal brittle stiffener, boundary constrains and steel frame beam size on elastic lateral stiffness were analyzed by using finite element software. Modified calculating formula of elastic lateral stiffness of SPWS was revised through comparing calculated results and test data. Based on modified calculating formula, the elastic simplified calculating model of SPWS was proposed, and the correctness was verified by finite element analysis. Results show that flexural link is the key factor to determine elastic lateral stiffness, and the simplified formula of elastic lateral stiffness and elastic simplified calculating model of SPWS have higher precision.
