| Abstract: | Prepared by the Structural Engineering Institute (SEI) of the American Society of Civil EngineersPrestandard for Performance-Based Wind Design presents recommended alternatives 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). Developed as a response to increasing interest in performance-based design (PBD), this prestandard aids in resolving conflicts in performance objectives that exist when using prescriptive procedures for the wind design and performance-based procedures for seismic design of individual buildings. It facilitatesdesign of more efficient buildings thatadhere todesired building functionality requirements and reduce property damage from wind while meeting public safety and performance requirements. 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.This document will be of benefit tostructural engineers, architects, building component and cladding specifiers/designers, and building officials engaged in the wind design and review of buildings. The prestandard also benefits building owners and developers, as wellas the general public. |
