摘要:
为研究设置水平拉结带和构造柱-圈梁对薄壁节能砌块薄灰缝组合墙体抗震性能的影响,共设计了9片墙体试件,对比分析了有无构造措施的薄灰缝组合墙体的抗震性能,研究了竖向压应力、洞口大小、洞口位置对墙体抗震性能的影响,并分析了其破坏机理。结果表明:设置水平拉结带和构造柱圈梁后组合墙体整体性增加,各阶段主要受力部位由上下区砌块墙体转变为端部构造柱,因此破坏主要集中在该部分;设置水平拉结带和构造柱圈梁的墙体抗震性能明显优于未设置该措施的墙体,承载力和变形能力均有较大幅度增加,滞回曲线饱满,刚度退化缓慢并有一定残余刚度,后期变形性能好;组合墙体洞口两侧破坏严重,洞口显著削弱墙体的承载力。
Abstract:
In order to study the influence of setting horizontal binding bands and constructional columnbeam on seismic behavior of thin motor composite wall with thin shell thermal block, nine wall specimens were designed.The seismic behaviors of walls were compared with or without horizontal binding bands and constructional columnbeam, and the influences of vertical compressed stress, size of opening and position of opening on the seismic behavior of masonry walls, and the failure mechanism were analyzed. The results show that the integral performance of the wall is increased through setting horizontal binding bands and constructional columnbeam. The bearing capacity changes from up and down parts of walls to the constructional column, so serious damage is concentrated in the constructional column. The seismic behavior of walls with horizontal binding bands and constructional columnbeam is obviously better than that without the construction, and the bearing capacity and deformation performance are increased, the hysteresis loops are plump, the stiffness degradation is slow and has residual stiffness, and the later deformation performance is good. The both sides of opening of composite masonry wall are seriously damaged, so the bearing capacity is weakened by opening.
