Ductility analysis for rectangular frame column subjected to bilateral shear force
Abstract：To investigate the ductility property and rigidity degeneration of rectangular frame columns（RFC）under bilateral horizontal load,a total of 7 RFC with different loading angle subjected to low-cyclic oblique horizontal load were tested.By analyzing the hysteresis loop and skeleton curve of RFC subjected to bilateral shear force and calculating the ductility coefficient of RFC with different loading angle through energy equivalent method,the results indicated that there were not different significantly for hysteretic loop of RFC subjected to oblique or forward horizontal load.With the increasement of loading angle,the ductility coefficient of RFC subjected to bilateral shear force were decreased.Moreover,all rectangular frame columns subjected to oblique horizontal load were failure in shear,which was brittle failure,and the anti-seismic design about RFC under oblique horizontal load should be enhanced.
