Gust-front factor: A new framework for the analysis of wind load effects in gust-fronts
In comparison with atmospheric boundary-layer winds, which are customarily treated as stationary, gust-front winds such as a thunderstorm/downburst exhibit strong nonstationarity. In storms characterized by a gust-front, wind speed changes rapidly during a short time period. In order to realistically describe attendant loads effects, a new analysis framework is presented which is named the gust...
متن کاملGust Loading Factor : New Model
Wind loads on structures under the buffeting action of wind gusts have traditionally been treated by the ‘‘gust loading factor’’ (GLF) method in most major codes and standards around the world. In this scheme, the equivalent static wind loading used for design is equal to the mean wind force multiplied by the GLF. Although the traditional GLF method ensures an accurate estimation of the displac...

متن کاملOn the formulation of ASCE7-95 gust effect factor
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. Exampl...
متن کاملMachine Intelligent Gust Front Detection
I] Techniques of low-level machine intelligence, originally developed at Lincoln Laboratory to recognize military ground vehicles obscured by camouflage and foliage, are being used to detect gust fronts in Doppler weather radar imagery. This Machine Intelligent Gust Front Algorithm (MIGFA) is part of a suite of hazardous-weather-detection functions being developed under contract with the Federa...
