Abstract:: Currently,most attentions was devoted to assessing seismic losses for newly-built or existing building structures with certain structural design schemes.Few studies were performed to take the seismic-loss estimation into account the architectural design of buildings especially for the architectural function arrangement.In this study,a nine-story,concentrically-braced frame structure was focused.The new generation of performance-based earthquake engineering theory was used to estimate seismic-loss risks.The differences in seismic-loss results for the considered seven building functional schemes that consist of commercial office,retail and apartment were discussed.Subsequently,an optimal decision approach based on the genetic algorithm was developed for determining architectural functions of buildings involving seismic-loss risk and the decision-maker’s initiative.The results show that the risk of the structure’s collapse in 50 years is as low as 0.64%.The selection of architectural function scheme of buildings has considerable effects on the economic losses under the seismic action.The largest relative difference can be up to 20%.
