Abstract

In this study, the effects of the inelastic shear behavior of beam-column joint, the vertical distribution of lateral load considering higher modes and masonry infill walls on the response of RC IMRF are evaluated in the pushover analysis, where 5-story structures were designed in accordance with KBC2009. M-${\phi}$ relationship for beam and column was identified with fiber model. An analytical model for inelastic beam-column joint was suggested and the behavior of the joint was reproduced with simple and unified joint shear behavior model. An inelastic masonry infill wall was simulated with two diagonal braces. Negligence of inelastic shear behavior of the joint caused overestimate of the maximum strength of the structures. The structures with masonry infill walls showed greater initial stiffness and maximum strength than those for the structure without the walls and the differences disappeared after the failure of the walls.
