A Framework for Performance-Based Wind Engineering
In traditional wind engineering design, the response of a building is essentially at or below the first significant yield point in some members of the lateral load resisting system under ASCE 7 Strength Level load combinations. Engineers have generally not considered pushing this threshold primarily because there is no established framework for consideration of inelastic behavior under wind loading. In buildings subjected to seismic loads, controlled inelastic response is permitted by the building codes for a safe and economically feasible design. The concept of allowing a controlled inelastic response could also be extended to the analysis and design of tall, slender buildings subject to wind loads, where the dynamic wind component is a significant portion of the total wind load. In this paper, a framework for performance-based wind engineering is proposed. Selection of building performance objectives, quantification of wind hazards and methods for explicit consideration of nonlinear behavior are outlined. The proposed methodology can be applied to evaluate the performance of existing buildings or to economically design new buildings subjected to wind loads.
