| Abstract: | Future performance-based seismic design, directly addressing the inelastic deformation induced in buildings by earthquake ground motions, should be based on probabilistic approaches. In recent years, reliability-based structural optimization has gained much research attention due to its advantages of accounting for the various sources of the uncertainties and approximation in design process. However, there is yet no effective method for reliability-based design optimization of concrete buildings subject to seismic performance criteria. This paper therefore presents an effective reliability-based design optimization approach for reinforced concrete buildings subjected to earthquake loading in which the structural performance is assessed at the system level by push-over analysis. Such developed approach, which integrates structural reliability theories with optimization technique, can provide a good balance between the structural reliability and the steel reinforcement cost under specified performance requirements. |
