Abstract
This study investigates the application of Performance-Based Wind Design (PBWD) to a representative building using linear and nonlinear time-history analyses with floor-by-floor time-series wind forces. The 1-year, 50-year, and 500-year return-period winds were used to evaluate occupant comfort, displacement serviceability, and structural safety, respectively. The linear analyses demonstrated that both acceleration and displacement responses satisfied the prescribed acceptance criteria. Under the 500-year wind, the nonlinear analysis revealed localized yielding and limited inelastic behavior, while residual displacement, interstory drift, deformation damage index, and fatigue demand remained within allowable limits. A pushover analysis further confirmed that a conventional wind-governed design may lead to brittle shear failure in critical members, whereas the PBWD-based design exhibited stable ductile behavior with improved structural reliability. The results highlight that PBWD provides a rational and resilient design framework, ensuring consistent structural performance for buildings governed by wind effects.
