钢板剪力墙简化模型研究

本文用斜拉杆简化模型分析了钢板墙从弹性屈曲到拉力带全部屈服的受力全过程。考虑了真实的拉力带倾角、塑性变形系数和屈服后阶段弹模折减等因素影响,用斜拉杆模型模拟了拉力带的受力过程,推导了斜拉杆初始屈服应力、极限应力、钢板墙剪力和位移计算公式,得到了钢板墙的弹塑性荷载-位移曲线,最后与试验资料比较验证了公式的有效性。

Study of Steel Plate Shear Walls Using the Simplified Model

A full shear resisting process of steel plate shear walls from elastic buckling up to yielding of tension field in the panel was investigated.The action of tension field was simulated by the strip model taking account of the effects of the angle of tension field,plastic deformation factor and post-initial yielding behavior modulus etc.Formulas for calculating initial yielding stress and ultimate stress of the strip,the shear and displacement at different stages for panels were derived.Thus,the load-displacement curve for steel plate shear walls at different stages was obtained.The effectiveness of the method proposed in this paper was demonstrated by comparing the predicted response with the results obtained from tests.
