This study aims to assess the seismic performance of typical reinforced concrete buildings constructed in Australia before the enforcement for seismic design. 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 buildings{\textquoteright} components is provided. Nonlinear time history analyses are conducted and {\textquotedblleft}cloud analysis{\textquotedblright} is used to develop the probabilistic seismic demand models. The results from the fragility assessment suggest that the low-rise buildings located on soft sites are the most vulnerable buildings.

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 {\textquoteleft}Cloud{\textquoteright} analysis. Finally, fragility curves are developed considering four different performance limits to assess the seismic risk of the buildings.

Mid-rise buildings in Australia typically have shear walls and cores as the primary lateral load resisting system and perimeter reinforced concrete moment resisting frames which form part of the gravity load resisting system. There are concerns about the displacement compatibility between the walls and the frames since in regions of low-to-moderate seismicity such as Australia insufficient consideration is given to the displacement capacity of the gravity load resisting systems. The gravity frames are mostly designed as ordinary moment resisting frames and thus have non-ductile detailing and are vulnerable to sudden undesirable failures. One of these failure mechanisms is due to the response of poorly detailed beam-column joints. Thus, the aim of this study is to investigate the effect of inelastic beam-column joint response on the displacement capacity of reinforced concrete gravity moment resisting frames designed in accordance with the Australian standard considering only the gravity load.
