With the new awareness that most Australian reinforced concrete (RC) buildings have not been designed to withstand seismic actions, and are considered to have limited ductility, it is essential to consider retrofitting options. This study aims to evaluate the seismic performance of an archetypal Australian RC building, and then implement various retrofit techniques to find the most suitable retrofit. The structural performance of the buildings before and after various retrofitting were compared to study the effectiveness of the proposed methods as well as the effect on the seismic hazard design factor. SeismoStruct software was used to perform the nonlinear analysis of the structures. This paper contributes to a research with the overall aim of assessing the seismic performance of existing buildings and their expected failure modes, impact of retrofitting measures, and the associated costs.
