Abstract：Three inclined column-shaped transfer floor structures of frame-supported short-leg shearwall are tested under vertical loading and horizontal cyclic loading to analyze the influence of leg-thickness ratio on the seismic performance of inclined column-shaped transfer floors. The failure process and patters, bearing capacity, hysteretic characteristics, stiffness degradation, deformation and ductility are analyzed in detail. The test results show that the force characteristic of inclined column-shaped transfer floor structure is similar to a simple truss, and leg-thickness ratio of the top short-leg shearwall has important implications to the transfer beam performance; if the design is reasonable, the inclined column-shaped transfer floor structure has a good ductility, multi-channel seismic line of defense and better seismic performance.
