摘要:
为研究小剪跨比内置钢管组合剪力墙(STLW剪力墙)的抗震性能,对STLW剪力墙试件进行低周反复加载试验,分析其破坏形态、破坏机理、变形能力、耗能性能、刚度及承载力退化规律. 然后,采用拉压杆-滑移模型对STLW剪力墙的承载力进行分析. 试验结果表明,在水平荷载作用下,STLW剪力墙由整截面墙渐变为开竖缝剪力墙,有效避免了小剪跨比钢筋混凝土剪力墙发生脆性剪切破坏.与传统小剪跨比剪力墙相比,STLW剪力墙的变形能力及耗能性能显著提高. 经合理设计,其极限位移可提高约50%,黏滞阻尼系数提高约2倍.STLW剪力墙承载力计算值与试验结果较符合,拉压杆-滑移模型能较好地反映STLW剪力墙受力机理.
Abstract:
To study the seismic behaviors of steel stub filled composite shear walls with low aspect ratio(STLW shear walls),the cyclic horizontal load experiments were carried out for the STLW shear wall specimens. The failure pattern,failure mechanism,deformability,energy dissipation capacity, stiffness and rigidity degeneration of the specimens were analyzed. Then, the capacity of the STLW shear walls was studied by using the softened strut-and-slip mode. The experimental results show that under the horizontal loads, the STLW shear walls can be transformed from the entire shear walls into the walls with vertical slits so that the shear failure of specimens can be avoided. Compared with the traditional shear walls with the low aspect ratio,the deformability and energy dissipation capacity of the STLW shear walls are improved. With proper construction,the ultimate drift ratio and the viscous damping factor increase by about 50% and 2 times,respectively.The calculation results for the capacity of the STLW shear walls are in good agreement with the experimental results. The softened strut-and-slip model can reflect the shear behavior of the STLW shear walls.
