【摘要】 通过分析四块屈曲约束开缝钢板剪力墙实验各参数,印证了对普通开缝钢板剪力墙所提出的初始刚度和极限承载力设计公式同样适用于屈曲约束开缝钢板剪力墙.由于面外约束构件的作用,屈服承载力应取开缝条带全截面屈服时刻而不是边缘屈服时刻.分析了第二刚度与第一刚度的相互关系,提出了屈曲约束开缝钢板剪力墙的双折线滞回模型.更多还原

【Abstract】 This paper confirmed the initial stiffness and ultimate bearing capacity of buckling restrained steel plate shear wall with slits by analyzing four specimens.The yielding capacity should be at the second when all section of the slit strip yields but not the second when the edge fiber yields.The relationship between the second and first stiffness was analyzed.A bilinear hysteretic model was put forward for buckling restrained steel plate shear walls with slits.更多还原
