Current practice in wind engineering of structures requires the lateral load resisting system to remain elastic during extreme events, such as hurricanes. There is increasing interest in allowing some inelastic response to occur, particularly in relation to performance based concepts that are under development by a variety of ASCE Committees, including the ASCE 7 Wind Subcommittee. This paper, developed by the ASCE Wind Division Task Committee on Performance Based Wind Engineering, discusses the motivation for allowing inelastic response under wind, and presents the implication of inelastic response on system performance. The work is based on theoretical concepts in wind loading and response, and example analysis of selected systems.
