钢筋混凝土短肢剪力墙抗震性能试验及应用

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.

Experimental research on aseismic behavior of RC short-leg shear wall and application

Short-leg shear wall (SLSW) is widely used at the buildings within 10 to 25 storeys. However, the national code gives few detailed items about the design of the SLSW. In light of that the theoretical study of the SLSW falls behind the practice, horizontal cyclic loading tests on six reinforced short-leg shear walls with 1:2 scale are carried out. The damage form and working capability of the samples show that the final damage of the samples are caused by the failure of the connecting beam, which is the weak part of the sample. The loading capacity of SLSW with flanged-wall is better than that without flanged-wall. The form selection and design of the SLSW of a high-rise building will be made with the guidance of the test results.
