带拉条多腔钢板混凝土组合剪力墙抗震性能研究
|
摘要
提出一种带拉条多腔钢板混凝土组合墙,为研究其抗震性能,设计制作该形式的组合剪力墙进行拟静力试验。通过改变试件的轴压比、高宽比,研究其在低周往复荷载作用下的破坏机理、滞回性能、耗能能力及刚度退化等,并以此试验为基础,建立有限元模型,分析了不同参数对其在往复荷载作用下工作机理和破坏模式的影响。结果表明:有限元模型与试验结果吻合良好,不同参数下该形式的组合墙均具有较高的承载力,较好的塑性变形能力和耗能能力,抗震性能良好。当轴压比低于0.6、高宽比低于2、拉条间距小于120 mm,同时混凝土强度等级取C50、钢材厚度取5 mm时,有利于试件抗震性能的发挥。
In this paper a study on multi-chamber steel plate-concrete composite wall with braces is presented. Specimens of shear walls were designed and fabricated initially, and quasi-static cyclic experiments were carried out afterwards to investigate its seismic behaviors. The failure mechanism, hysteretic behavior, energy dissipation capacity and stiffness degradation under low cycle reversed loads were investigated by changing the axial load and aspect ratios. A finite element model was established based on experimental results, and the influence of different parameters on working mechanism and failure modes were further analyzed under low cycle reversed loads. The results show that the finite element model satisfy suitably with the experimental results, and that the composite shear walls with different parameters have high bearing capacity, high plastic deformation and energy dissipation capacity, and thus strong seismic performance. The best seismic performance is shown with specimens having the axial load ratios lower than 0.6, aspect ratios lower than 2, spacing of braces less than 120 mm, concrete strength of C50, and steel thickness of 5 mm.
