摘要:
为了研究低层装配式钢筋混凝土水平坐浆墙体的抗震性能,对3个不同剪跨比的低层装配式钢筋混凝土水平坐浆墙体进行了低周反复荷载试验。根据试验结果,分析了剪跨比对墙体的破坏形态、承载力、变形能力、刚度退化和耗能能力的影响。结果表明:随着剪跨比的减小,墙体的破坏形态由弯曲破坏转为剪切破坏;试件SW2和试件SW3的承载力相对于试件SW1分别提高68%和110%,延性分别降低21.8%和37.5%;试件SW1的耗能能力最好,刚度退化速度最缓慢;预制钢筋混凝土墙板与现浇边缘构件协同合作,连接处无竖向裂缝,墙体整体性较好,具有良好的抗震性能,可用于我国城镇建设中的低层住宅结构。
Abstract:
In order to study the seismic performance of low-rise fabricated reinforced concrete walls with horizontal mortar connection, three walls of this kind with different shear span ratios were tested subjected to low-cycle loading. The effects of shear-span ratio on the wall, failure mode, bearing capacity, deformation capacity, stiffness degradation and energy dissipation capacity are analyzed based on the test results. The results show that the wall failure mode changes from the bending failure to the shear failure with the decrease of shear-span ratio. Compared with SW1 specimen, the bearing capacity of the specimens SW2 and SW3 increases by 68% and 110%, and the ductility decreases by 21.8% and 37.5%, respectively. The SW1 specimen has the largest energy dissipation capacity and the smallest stiffness degradation rate. The fabricated reinforced concrete wall panels work together with cast-in-situ edge members without vertical cracks at the joints. The wall has good integrity and seismic performance, and can be applied to the low-rise residential structures in urban construction in China.
