该文对4个两边连接钢板组合剪力墙在滞回荷载作用下的性能进行了试验研究。研究了混凝土板与角钢端部的间距以及端部设置加劲肋对两边连接钢板组合剪力墙力学性能的影响。试验结果表明:在钢板角部设置短加劲肋能有效提高构件的延性和耗能能力,相比不设置加劲肋试件,最大层间侧移角由1/35提高到1/25,能量耗散系数提高了35%。混凝土板和角钢的间距也影响构件的受力性能,设置的过大或过小都会使试件节点过早出现破坏。
In this paper, the experimental research on the performance of four combined shear wall with steel plates under hysteretic loading is carried out. The effects of the spacing between the concrete slab and the end of the angle steel and the stiffener at the end are studied on the mechanical properties of the composite shear walls connected to the two sides. The experimental results show that the short stiffeners at the corners of the steel plate can effectively improve the ductility and energy dissipation capacity of the members. Compared with the test without stiffener, the maximum lateral drift angle increases from 1/35 to 1/25, and the energy consumption The coefficient of dispersion is increased by 35%. The distance between the concrete slab and the angle steel also affects the force-bearing performance of the component. If the setting is too large or too small, the node of the specimen will prematurely break down.
