本文对分别设置构造柱和芯柱的整体、开窗洞、开门洞的三类加气混凝土砌块墙进行了拟静力抗震试验,比较两种抗震构造措施对墙体抗震性能的影响。具体研究了水平荷载下的各墙体的破坏过程,通过试验得到了滞回曲线,讨论了各墙体的抗剪承载力、变形性能和耗能能力等性能指标,分析了不同构造措施下墙体的抗震性能差异。试验表明,在墙体两端设置构造柱墙体的抗震抗剪承载力高(包括开裂荷载和极限荷载),刚度较大;在墙体两端和洞口两侧均设置芯柱的墙体由于洞口处有芯柱约束,后期承载力下降缓慢,有更好的后期变形能力;在耗能方面两者能力相当。
In this paper, quasi-static tests on three types of aerated concrete masonry walls with integral columns, fenestration holes and open-door cavities are carried out respectively. The influences of two seismic structures on the seismic performance of the wall are compared. The failure process of each wall under horizontal load is studied in detail. Hysteresis curves are obtained through experiments. The performance indexes such as shear capacity, deformation capacity and energy dissipation capacity of each wall are discussed. Seismic performance of the body difference. The test results show that the seismic load-bearing capacity of the structural column wall at both ends of the wall is high (including the cracking load and the ultimate load), and the rigidity is high. The wall with the core columns at both ends of the wall and both sides of the hole Core hole at the hole constraints, the late bearing capacity decreased slowly, with better post-deformation capacity; both in terms of energy consumption capacity.
