摘要
本文在对比单层等高开缝钢板剪力墙与双层等高开缝钢板剪力墙受力性能的基础上,建立了"梭形"、"凸形"、"蝶形"、"凹形"等4种双层不等高开缝钢板剪力墙,对其进行往复水平荷载作用下的受力性能研究,通过对比分析其滞回曲线、骨架曲线及能量耗散系数等参数,研究了4种开缝形式对钢板剪力墙的影响。结果表明:相同开缝率下的双层开缝钢板剪力墙受力性能优于单层开缝形式,抗侧刚度及承载力和耗能能力均得到提高;双层不等高开缝形式钢板剪力墙抗侧刚度、累积滞回环面积、承载能力均较等高双层钢板剪力墙大幅提高,其中"凹形"不等高开缝形式最佳。
On the basis of comparing the mechanical performance of single-row of equal-length slotted steel plate shear wall,four double-row of unequal-length slotted steel plate shear wall are established to study their mechanical performance under reciprocating horizontal loads. By comparing and analyzing the hysteresis curves, skeleton curves, energy dissipation coefficients and other parameters,the influences of four types of slits on steel plate shear walls are studied.The results show that the mechanical performance of the double-row slotted steel plate shear wall under the same slit ratio is better than that of the single-row slit form,and the initial lateral stiffness,bearing capacity and energy dissipation capacity are improved;compared with the double-row steel plate shear wall of equal-length the initial lateral stiffness,cumulative hysteretic loop area and bearing capacity of the steel plate shear wall with unequallength double-row slotted steel plate shear wall are greatly improved.It is found that the"concave"unequal height slit form is the best slit form.
