摘要

Performance-based wind design (PBWD) allowing inelastic behavior under extreme wind load has only been recently considered for design of high-rise buildings. Unlike performance-based seismic design, there are few guidelines and research on inelastic wind design. Time-history wind loads for PBWD rely on wind tunnel tests. However, conducting wind tunnel tests for preliminary structural concepts may not be practical due to changes in design and cost. To address these concerns, the following topics were studied: initial design using an R-W factor to introduce inelastic behavior; generation of time-history wind loads from power spectral density (PSD) functions for inelastic analysis including vertical distribution and maximum directional load occurrence, and a case study for wind resistance performance evaluation of a reinforced concrete building design using an R-W factor of 1, 2, and 3.
