The most common structural system for apartment buildings in Korea is adopted to combine structural systems: for example, a moment-resisting frame will be used for lower stories and bearing wall system for the upper stories. This type of buildings have soft and/or weak stories in lower stories, and it may lead to collapse of those buildings during the large earthquake. Horizontal cyclic load tests were conducted to estimate the strength, ductility, and behavioral characteristics of deep beam and interior column joints. Experimental parameters are axial forces (0.3P?, 0.2P?) and amount of transverse reinforcement (designed by ACI code and Sheikh's procedure). This study concluded that (1) As the axial forces of column increase from 0.2P? to 0.3 P?, the resisting lateral load increase, but the curvature ductility was reduced. (2) Up-lift and flexural deformation at the hinge region contributes to 70% ~ 80% of total lateral deformation. (3) The required amount of transverse reinforcement of column designed by Sheikh's procedure requires 3.2 times larger than that designed by ACI code. (4) Curvature ductilities of the specimen designed by Sheikh's procedure were 9.36 and 5.43 for 0.2P? and 0.3P?, respectively, which are lower than those predicted according to Sheikh's procedure, 10 for 0.4P? and are 1.1 and 1.16 times larger than those designed by ACI procedure. These show that the curvature ductilities in columns are affected by axial forced than by the amount of transverse reinforcement.
