Prestandard for Performance-Based Wind Design developed by the Structural Engineering Institute (SEI) of the American Society of Civil Engineers (ASCE) presents a recommended alternative to the prescriptive procedures for wind design of buildings contained in the nationally adopted standard Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE 7) and in the International Building Code (IBC). The intended audience for this document includes structural engineers, architects, building component and cladding specifiers/designers, and building officials engaged in the wind design and review of buildings. Properly implemented, this prestandard results in buildings that are capable of achieving the wind performance objectives
specified by ASCE 7, and in many instances, superior performance to such objectives.
SEI has published the first edition of this prestandard in response to the increasing interest in using performance-based approaches for the design of buildings. In addition, this prestandard aims to help resolve conflicts in performance objectives that exist when using prescriptive procedures for the wind design and performance-based procedures for the seismic design of individual buildings. Major innovations introduced include nonlinear dynamic analysis for wind design, limited inelasticity in the Main Wind Force Resisting System elements, system-based performance criteria, and enhanced design criteria for the building envelope.
