摘要

Performance-based wind design (PBWD) is an evolving research area aiming for a unified methodology for designing structures with predictable behavior. This field draws insights from performance-based seismic engineering, recognizing distinct challenges in applying these principles to wind engineering. Various studies propose deterministic and probabilistic approaches for wind hazard analysis and performance-based design methodologies. These studies explore modeling uncertainties in the performance evaluation process, often extending concepts from seismic design to wind scenarios. Two crucial factors are the number of inelastic cycles induced by wind and the consequential degradation of strength and stiffness. Analyzing the inelastic structural response in the time domain is essential, offering an understanding of energy absorption and force redistribution. The integration of experimental studies with numerical analyses is imperative for comprehending the particulars of performance-based design in wind engineering and navigating the boundaries of nonlinear analyses. This work aims to study the integration of seismic design concepts with the wind effect through a literature review of the methodologies proposed so far for performance-based wind engineering. The framework proposed by Elezaby and El Damatty with a coupled wind/seismic notion is presented to discuss the ductility-based approach for wind loads and future work considering different types of analysis. The first step of the methodology, which includes the evaluation and de-composition of elastic straining actions based on wind tunnel testing and finite element modeling, is analyzed using the case of study an irregular 19-story reinforced concrete building previously tested at The University of Western Ontario’s Boundary Layer Wind Tunnel Laboratory.
