侧边加劲带缝钢板剪力墙滞回性能研究
|
摘要
带缝钢板剪力墙延性好、耗能能力强,是一种性能优良的新型抗震组件。采用数值模拟对边缘加劲带缝钢板剪力墙的滞回性能进行研究,系统分析了各种特征参数对墙板刚度、承载力及耗能能力等的影响,并在此基础上提出设计建议。分析表明:实现屈曲前屈服是带缝钢板剪力墙兼具高延性和高耗能能力的必要条件;减小缝间墙肢宽度与墙板高度之比,或增大缝间墙肢高度与墙板高度之比,将有利于墙板实现屈曲前屈服;随开缝参数不同,墙板的面外变形形态分为两类;增大肋板刚度比可显著增大发生整体失稳墙板的延性;在保证自身局部屈曲不早于墙板整体屈曲发生的前提下,为方便取材,加劲肋应首选与墙板同厚的钢板。
With the advantages of high ductility and energy dissipation capability,the steel plate shear wall with slits becomes a new earthquake-resisting component.Hysteretic behavior of stiffened steel slit wall was analyzed numerically in this paper.Parameters affecting stiffness,strength and energy dissipation capacity of steel slit wall were investigated.Based on the simulated results,some designing suggestions were given.The results show that in order to achieve good anti-seismic performance,the steel slit wall should be designed to undergo full plastic deformation prior to the out-of-plane buckling.It can be achieved by decreasing the ratio of limb width to the wall height,or increasing the ratio of limb height to the wall height.The out-of-plane deformation of steel slit wall changes with the tier number of slitting.With the increment of the stiffeness ratio of stiffeners to infill steel plate,the ductility of steel slit wall was significantly improved.As for the stiffener,it thickness is recommended to be identical to that of the infill steel plate if its buckling is guaranteed to be posterior to the overall buckling of steel slit wall
