摘要
仅与框架梁相连的钢板剪力墙侧边易发生屈曲,对侧边进行加劲可提高其屈曲承载能力。对边缘方钢管端柱加劲的480个钢板剪力墙弹性屈曲性能进行分析,研究端柱刚度对剪力墙屈曲模态的影响,分析方钢管端柱加劲钢板剪力墙弹性屈曲性能要求和端柱门槛刚度确定方法;通过有限元方法求解方钢管端柱加劲剪力墙弹性屈曲系数,并对影响因素进行分析,给出弹性屈曲系数计算式。
The steel shear walls only connected with beams are prone to buckle and their buckling bearing capacity can be improved by adding stiffeners at side edges. The elastic buckling behaviors of 480 shear walls stiffened by adding side columns were investigated. The effects of side column stiffness on buckling modes were compared and the critical stiffness of side columns was studied. According to the finite element analysis results,buckling coefficients of shear walls with side columns were determined and effecting factors were investigated. Finally,a formula to predict buckling coefficients was proposed.
