Description
Summary:•A performance-based design framework for wind-excited buildings is proposed.•The framework is defined to treat a wide class of building systems.•The approach integrates probabilistic loss models with dynamic shakedown theory.•The method efficiently accounts for the possibility of inelastic collapse.•A case study is presented demonstrating the potential of the proposed framework. Current prescriptive design provisions are moving towards performance-based design approaches in which system-level probabilistic measures are used to explicitly describe performance. While earthquake engineering has embraced these changes over the last few decades, the same cannot be said for wind engineering where design provisions have remained predominantly prescriptive. The significant wind related economic losses incurred each year around the world has spurred strong interest in developing general performance-based wind engineering frameworks. To this end, this paper presents a simulation-based framework for multistory wind excited buildings that rigorously integrates system-level estimates of both collapse and non-collapse losses. In particular, it is proposed to use the theory of dynamic shakedown as an efficient means for describing the collapse probability of the main wind force resisting system. The practicality and potential of the proposed framework is illustrated on a full scale case study.
