Abstract

ABSTRACT: Effect of different proportioning of lateral force-resisting system in the orthogonal directions, on seismic collapse capacity and fragility of reinforced concrete buildings is investigated. Buildings with different structural systems and configurations, are designed for a modern seismic design code. To simulate the structural collapse, the hysteretic models of beams, columns, and shear walls are duly calibrated using experimental tests results. Results show that if the buildings of a given height are designed for the same hazard level, these show equal levels of safety against collapse, irrespective of the proportioning of lateral load resisting systems in the orthogonal directions.
