往复荷载下小砌块墙体抗震性能的试验研究

Seismic Behavior of Small Hollow Concrete Block Walls under Low-cyclic Loadings

采用L9(34)正交试验设计方法,通过9个小砌块墙体试件的低周往复加载,对墙体抗震性能进行试验研究。试验结果表明:小砌块能量耗散水平的最主要影响因素是墙体的高宽比,其次是芯柱数量。研究结果对小砌块墙体抗震设计和研究具有一定的参考价值。

By using statistical methods of orthogonal experimental design and analysis, nine specimens of the small hollow concrete block walls were tested and some of the important seismic behaviors of the walls were analyzed. The analysis results showed that theenergy dissipation capacity of the small hollow concrete block walls is mainly determined by the aspect ratio of the walls, and also affected by the number of grouted strips in a minor degree. The research findings give some valuable suggestions to the seismic design of masonry walls.
