The document discusses performance-based wind analysis and design of structures. It provides a literature review of research on using nonlinear analysis methods and performance-based approaches for wind loading, which consider structural responses in the nonlinear range. These methods allow for controlled inelasticity and aim to more efficiently design structures to meet performance requirements under varying wind loads. The review found that while performance-based seismic design is common, performance-based wind design requires further investigation, particularly for defining wind load patterns for nonlinear analysis.
