摘要
选择9种单榀单跨带缝钢板剪力墙结构单元在水平正弦周期往复荷载作用下进行受力性能分析,总结开缝设计参数比h/b、h/H、hm/hd对带缝钢板剪力墙受力性能的影响,并选出参数比h/b、h/H、hm/hd下的最佳比值。结果表明:h/b=5时的带缝钢板剪力墙结构单元的侧移刚度、承载能力大,抗侧能力强,滞回性能好,耗能能力强;当h/b=5一定时,h/H=0.29的带缝钢板剪力墙结构单元的承载能力大,滞回性能好,耗能能力强;当其他开缝设计参数一定时,hm/hd=1.67时的带缝钢板剪力墙结构单元的延性大,滞回性能好,耗能能力强。
It is analyzed that the mechanical performances of 9 single-span plate shear walls with slits under horizontal sine cyclic reciprocating loads;the effects of the designed parameter ratios h/b,h/H and hm/hd on the mechanical performances of these shear walls are summarized.The results show that:when h/b=5,the lateral stiffness and the load-carrying capacity of the plate shear wall with slits are high,the power of the lateral resistant ability is strong,the ability of the hysteretic performance is good and the ability of energy-dissipation is strong;when h/b=5 is fixed,the plate shear wall with slits whose h/H=0.29 has strong load-carrying capacity,good hysteretic performance and strong ability of energy-dissipation;when other designed parameters of the plate shear wall with slits are fixed,hm/hd=1.67,the ductility of the plate shear wall with slits is strong,the hysteretic performances is good and the ability of energy-dissipation is strong.
