摘 要:提出了一种适用于低层建筑的装配式剪力墙结构,并对3个足尺预制剪力墙试件进行了低周往复加载试验。结果表明:在合理范围内增加轴压比, 墙体的承载力有明显提高,两个试件都是延性破坏,延性和耗能能力均有所增强;减小剪跨比会使墙体开裂荷载和原始刚度变大,但延性变差, 水泥砂浆层出现脆性破坏。
Abstract: A prefabricated shear wall structure for low rise buildings was put forward, low cyclic loading experiments were conducted on three full-scale precast shear wall specimens. The results show that with the increase of axial pressure ratio, the bearing capacity of the low-rise precast concrete shear wall specimen can be enhanced obviously. Two walls are ductile failure and the ductility and energy consumption capacity are slightly enhanced. Reduction of shear span ratio of wall can improve the cracking performance and initial stiffness, which can obviously reduce the ductility of the wall, and the shear slip failure of the cement mortar is produced.
