Performance-Based Wind Engineering: Background and State of the Art

Abstract

This paper surveys the rapidly growing field of performance-based wind engineering (PBWE) of engineered systems, with focus on not only how PBWE has evolved since its early incarnations inspired by performance-based seismic engineering, but also the unique challenges of PBWE and the research that continues to emerge to tackle them. The limitations of traditional prescriptive wind design approaches are discussed with the aim of illustrating how such approaches are inadequate for providing acceptable building performance during extreme wind events, thus motivating why performance-based strategies for wind engineering are gaining traction and are poised to complement, if not replace, current approaches to wind design. In this respect, the current state of knowledge on the factors that affect building performance via extreme structural response, damage to the envelope system, and nonstructural components, is reviewed and challenges are identified. Lastly, the potential benefit of integrating optimization methods is identified while acknowledging the computational difficulty associated with such approaches.

Multi-objective Performance Based Control of Building Frames during Wind and Earthquake Events for Multi-Hazard Mitigation using a New Hybrid Passive Energy Dissipation Device

“…Immediate Occupancy (IO), Life Safety (LS) and Collapse Prevention (CP) that need to be fulfilled by the structure when subjected to various stipulated seismic hazard levels [4,5,6,7,8]. In recent years, performance based design (PBD) for wind engineering has gained significance in the emerging structural design philosophy and few performance based wind resistant design (PBWD) frameworks have been proposed by researchers in last two decades [9,10,11,12]. Recently, a pre-standard for performance-based wind design ASCE 2019 [13] was published in which performance objectives for PBWD were expressed in terms of rational performance limit states for wind events i.e.…”

Peak Inelastic Displacement of Bilinear Systems in Support of Performance-Based Wind Design

“…The performance-based design of buildings has evolved beyond the consideration of earthquakes to consideration of additional natural hazards, particularly windstorms [1]. This evolution in design is reflected by the many performance-based frameworks that have been proposed for wind engineering [1][2][3][4][5][6][7][8][9][10]. An important aspect of building performance is inelastic behavior.…”
