heal.abstract	A new approach for the performance-based seismic design of buildings using a structural optimization framework is proposed. Incremental Dynamic Analysis (IDA), one of the most powerful seismic performance estimation methods, requires numerous nonlinear response history analyses and thus often is not practical for the seismic design of buildings. To overcome the increased computing cost of IDA we adopt an approximate seismic performance estimation tool, known as Static Pushover to IDA (SPO2IDA). The SPO2IDA tool is nested within the framework of a Genetic Algorithm resulting to an efficient tool for seismic design. The Genetic Algorithm is able to locate the most efficient design in terms of the minimum weight of the structure. A three and a nine-storey steel moment resisting frames are used to demonstrate the design algorithm proposed. The proposed methodology leads to the efficient building designs within reasonable computing time and therefore is suitable for practical design applications. © 2011 Taylor & Francis Group, London.	en
