Abstract

In this study, the effects of the inelastic shear behavior of beam-column joint and masonry infill walls on the response of RC IMRF are evaluated in the inelastic time history analysis, where 5-story structures were designed in accordance with KBC2009. M-${\phi}$ relationship for beam and column was identified with fiber model, the behavior of the joint was reproduced with simple and unified joint shear behavior model and an inelastic masonry infill wall was simulated with two diagonal braces. The hysteretic behavior was simulated with three-parameter model suggested in IDARC program. The analytical results showed that the effect of beam-column joint and masonry wall on the structural behavior was trivial and that the inelastic shear behavior of the joint could be neglected in the structural design for seismic design category C but the structure of category D did not satisfy the criteria of FEMA 356 for collapse prevention performance level.
