Performance-based wind engineering (PBWE) is undergoing a period of rapid growth with multiple frameworks being proposed over the past decade. This has created increasing interest from industry in applying PBWE during the design process. This seminar will focus on recent advances in PBWE for modeling the nonlinear behavior of the structural system of engineered buildings subject to severe winds, as well as on approaches for modeling the damage and losses to the building envelope during such events. Firstly, computational approaches will be discussed for efficiently modeling the nonlinear time history response of structural systems subject to dynamic wind loads of long duration.
The potential of these approaches for enabling rapid propagation of uncertainty through nonlinear structural systems using stochastic simulation will be illustrated. Secondly, computational models for the performance assessment of the envelope system of engineered buildings during severe wind events, such as fragility-based progressive damage models and CFD-based Eulerian multiphase wind driven rain models, will be illustrated. The possibility of embedding these models in conditional stochastic simulation frameworks for the estimation performance metrics associated with rare events will also be discussed.
