EXPERIMENTAL STUDY ON THE SEISMIC BEHAVIOR OF CORNER JOINT IN STEEL REINFORCED CONCRETE SPECIAL-SHAPED COLUMN FRAME
The low-cyclic reversed loading tests of 4 comer joints in SRC special -shaped column frame were carried out. The mechanical behaviours and failure patterns of corner joint in SRC special-shaped column frame were analyzed. Characteristics of the hysteretic curves of load-displacement relation and load-strain relation of the steel bar are analyzed,and displacement ductile coefficient and equivalent viscous damping coefficient of the joints are discussed. It indicates that the loaddisplacement hysteretic curves of the specimens are symmetric and plump,and the capacity and seismic behaviours of the joints are higher than those of joints in RC special -shaped column frame. This study can be helpful for the analysis of mechanism and the establishment of calculating method of corner joint in steel reinforced concrete special-shaped column frame.
