短肢剪力墙结构体系广泛应用于10~25层的住宅工程中,然而现行的设计规范少有关于短肢墙的具体条文.针对短肢剪力墙结构体系理论研究落后于实际应用的情况,通过对6片1∶2单层短肢墙试体的低周反复荷载试验,研究了在低周反复荷载作用下钢筋混凝土短肢剪力墙的整体工作性能、破坏形态及延性.结果表明试件的最终破坏均是由连梁失效引起,连梁是短肢剪力墙结构的薄弱部位;带翼墙短肢墙结构的受力性能优于无翼墙结构.将试验研究成果用于指导某工程中短肢剪力墙的选型,并提出了设计建议.
The short-limb shear wall structure system is widely used in residential buildings of 10 to 25 storeys, however, there are few specific provisions on the short-limb wall in current design codes.Aiming at the shortcomings of theoretical research on the structural system of short-limbed shear walls lagging in practical application Through the low-cycle cyclic loading test of six 1: 2 single-wall short-limb wall specimens, the overall performance, failure mode and ductility of the reinforced concrete short-limbed shear wall under low cyclic loading were studied. The ultimate failure of the specimens is caused by the failure of the connecting beam, even the beam is the weak part of the short-limb shear wall structure. The mechanical performance of the short-limbed wall structure with wing walls is better than that without wing structure. Guide the selection of short-limb shear walls in a project, and put forward design proposals.
