斜柱式与梁式转换层结构的抗震试验分析

为了研究框支短肢剪力墙斜柱式与梁式转换层结构的抗震性能,分别对一榀框支短肢剪力墙斜柱式转换框架及一榀相同尺寸的梁式转换框架进行了竖向荷载和水平低周反复荷载共同作用下的拟静力试验.试验结果表明:斜柱式转换结构传力直接,可有效减小转换梁尺寸,且更易实现"强柱弱梁,强剪弱弯,更强节点"的抗震设计原则.斜柱式转换结构转换层侧向刚度较大,不易使转换层形成结构薄弱层;斜柱式转换结构,只要设计合理,可以获得较好的抗震性能.

Experimental Analysis on Seismic Behaviors of Inclined Column-shaped and Beam-shaped Transfer Floor

In order to analyse seismic behaviors of inclined column-shaped and beam-shaped transfer floor,the pseudo static testing is carried out,which are subjected to vertical loads and horizontal cyclic loads,respectively on two specimens,including the framed short-leg shear wall inclined column-shaped transfer plane framework and the same dimension beam-shaped transfer frame.The load transfer is direct,inclined column transfer structure can reduce the beam dimension effectively,and it is easier to implement the aseismatic design principles,including "strong column and weak beam,strong shearing and weak bend,stronger nodes".Lateral rigidity of inclined column-shaped transfer stories is large,making it difficult to engender structure weakness stories.If the design is reasonable,inclined column-shaped transfer structure can get better seismic behavior.
