Abstract

The aim of this study is to assess the seismic performance of limited ductile reinforced concrete buildings in line with performance-based earthquake engineering principles. Limited ductile RC buildings are vulnerable to undesirable and sudden brittle failures which need to be considered in nonlinear models. The response of both the primary lateral load resisting system and the gravity load resisting system is considered. A brief description of the modelling approaches adopted to simulate the response of the core walls and frame components in a macro-finite element modelling space is provided. Using the adopted approach the seismic performance of two generic buildings with a symmetric plan is assessed. Nonlinear time-history analyses are conducted to obtain the building response to seismic ground motion. Probabilistic seismic demand model is developed using ‘Cloud’ analysis. Finally, fragility curves are developed considering four different performance limits to assess the seismic risk of the buildings.
