Comparative Study on the Pseudo Static Testing of Beam Transfer Structure of Frame-Supported Short-Leg Shearwall with and without Haunch
In order to analyse seismic behaviors of the haunched beam-shaped transfer floor, carried out the pseudo static testing, which were subjected to vertical loads and horizontal cyclic loads, respectively on two specimens, including the framed short-leg shear wall haunched beam-shaped transfer plane framework and the same dimension unhaunched beam-shaped transfer frame. The test shows that: 1) Haunched beam-shaped transfer structure can apparently improve the shear-bearing-capacity of the abutment section and 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”; 2) if the design is reasonable, haunched beam-shaped transfer structure can get better seismic behavior.
