Determining wind loads under involves a systematic procedure to convert atmospheric wind speeds into design pressures for structural systems. Unlike later versions (ASCE 7-10 and beyond) that use ultimate wind speeds, ASCE 7-05 utilizes a single basic wind speed map based on service-level 3-second gusts, adjusted by an importance factor and a wind-load factor of 1.6 for strength design.
