Highlights of the formulation of the gust effect factor in recent revisions of the wind load provisions in ASCE7-95 are presented. The revised wind map is based on 50-year peak gust speeds in contrast with fastest mile speeds used in ANSI/ASCE7-93. The concepts of spatial and temporal averages are discussed, and the new gust effect factor (GEF) is introduced with its derivation detailed. Examples to illustrate the use of the new provisions in ASCE7-95 for flexible structures are provided.
