摘要
针对深圳梅山苑7号楼钢板剪力墙上开洞问题,对开洞闭口加劲钢板剪力墙进行了有限元研究,给出了不同开洞位置和不同开洞率钢板剪力墙荷载-侧移曲线,分析了开洞位置和开洞率对初始刚度、屈曲荷载和极限荷载的影响。研究表明,中间开洞对钢板剪力墙刚度和极限承载力影响较大,可以采用线性公式计算开洞对钢板剪力墙初始刚度、屈曲荷载和极限荷载的折减。
With respect to the openings in the steel plate shear walls（SPSWS） of No.7 building of Meishanyuan in Shenzhen,the behaviour of closed stiffened steel plate shear wall with opening was studied with finite element method.The load-displacement relationships of the shear walls were obtained for different opening positions and opening ratios.The effect of opening positions and opening ratios on the initial stiffness,buckling resistance and ultimate resistance of the steel plate shear walls was analyzed.The result shows that steel plate shear walls experience a progressive reduction in stiffness and strength with an increase of the opening size.The reduction factors for initial stiffness,elastic buckling load and ultimate bearing capacity of steel plate shear walls can be calculated by linear formulas.
