进行了三个钢筋混凝土墙试件的试验分析,以研究人工地震荷载下轴压比和约束对其性能的影响。对高宽比为4,由高强混凝土制成的高纵向比的薄垂直悬臂墙体进行了试验。详细研究了轴压比和约束对失效模式、延性、强度降低、轴压承载力的影响。通过研究,确定轴压比为混凝土剪力墙抗震性能评估的必要参数。同时简要地讨论了轴压比对矩形剪力墙的安全期、预防坍塌以及坍塌水平标准的影响。
The experimental analysis of three reinforced concrete wall specimens was carried out to study the influence of axial compression ratio and restraint on the performance under artificial earthquake load. A test was conducted on a thin vertical cantilever wall with a high aspect ratio of 4 and a high aspect ratio made of high-strength concrete. The effect of axial compression ratio and restraint on failure mode, ductility, strength reduction and axial compression bearing capacity are studied in detail. Through the research, it is determined that the axial compression ratio is the necessary parameter to evaluate the seismic performance of concrete shear walls. At the same time, the effect of axial compression ratio on the safety of rectangular shear wall, prevention of collapse and standard of collapse is discussed briefly.
