【摘要】 两边连接开缝钢板剪力墙具有延性好,耗能能力强等优点,同时有效避免了四边连接钢板剪力墙对框架柱产生的附加荷载,避免了与剪力墙相连框架柱的早期破坏。该文对两边连接开缝钢板剪力墙的弹性屈曲性能进行分析,系统考察了缝间小柱高宽比、宽厚比、开缝排数等参数的影响;同时分析了缝间小柱的屈曲性能,给出缝间小柱端部先于钢板整体弹性屈曲时的临界高厚比限值;分析结果表明,开缝钢板剪力墙保持平面内工作且通过缝间小柱端部形成塑性铰承担荷载并耗能时的理想开缝原则为缝间小柱宽厚比b/t<15且高宽比h/b>3.0。更多还原

【Abstract】 Steel plate shear walls with slits have good ductility and energy dissipation ability.As shear walls are not connected to frame columns,the premature overall buckling or local buckling failure of columns can be prevented.This paper presents the elastic buckling analysis of steel plate shear walls with slits connected with frame beams only.The influences of the width-to-thickness ratio and depth-to-width ratio of slit columns,and slit rows were analyzed.Also,the behavior of a slit column is studied to get the maximum height-to-thickness ratio when plastic hinges form at the bottom of the slit column.The results show that the steel plate shear wall with slits works in a plane if the slit height-to-width ratio is over 3.0 and the slit height-to-thickness ratio is less than 15.更多还原
