Performance based design is recognized as a reliable method for realistic seismic assessment of structural systems. Performance based design requires nonlinear time-history analysis which includes the nonlinear response of structural elements under cyclic loads. While nonlinear time history analysis is more time consuming and demands more technical expertise, it provides a more transparent assessment of the seismic response of the structures and leads to a more economical design. With increasing efficiency of analysis tools and computational power, performance based seismic design can be incorporated as an efficient tool in practice for the seismic design and retrofit of structures. This paper reviews the limitations of the force-based methods of analysis that are common in current practice and the advantages of nonlinear time history analysis. The proposed guidelines for performing a nonlinear time history analysis as well as the guidelines for the selection and scaling of ground motion records are reviewed. Finally, the nonlinear response of 3 case study buildings as well as the adopted retrofitting strategies, using the reference design codes such as the National Building Code of Canada (NBCC 2010) and the American Society of Civil Engineers (ASCE 7-10) are presented and discussed. Recommendations for the use of nonlinear time history analysis, as a design tool, are made to assist practitioners in the application of these methods.
