为了研究短肢剪力墙的抗震性能,对6个1/2比例的T形短肢剪力墙试件进行了低周反复荷载作用下的试验研究,分析了短肢剪力墙的承载力、延性、滞回特性、耗能能力及破坏机制等抗震性能。结果表明:短肢剪力墙试件以弯剪破坏为主,截面高厚比较大试件的腹板中部易发生剪切破坏;腹板底部是试件最薄弱部位,加暗支撑可明显增加试件的延性和极限承载力;随着试件轴压比的提高,试件延性降低,极限承载力增加。
In order to study the seismic behavior of the short-leg shear walls, six 1/2 T-shaped short-leg shear wall specimens were subjected to low-cycle repeated loading tests, and the bearing capacity of the short-leg shear wall , Ductility, hysteresis characteristics, energy dissipation capacity and failure mechanisms such as seismic performance. The results show that the specimens of short-limbed shear walls are dominated by bending and shear failure, and the shear failure is likely to occur in the middle of the specimens with high section thicknesses. The bottom of the webs is the weakest part of the specimens, The ductility and ultimate bearing capacity of the specimens are improved. With the increase of the axial compression ratio, the ductility of the specimens decreases and the ultimate bearing capacity increases.
