Each revision made changes and adjustments in several different factors including the importance factor, terrain factor, directionality factor, gust effect factor and the pressure/force coefficients.

The most significant change is the reference wind speed, which changed from fastest-mile to a 3-second gust. Major changes occurred in the wind load criteria in ANSI A 58.1-1982 and in ASCE 7-95. Since then, the wind load criteria have gone through major changes as revisions of the standard were made in ANSI A58.1-1982, ASCE 7-88, ASCE 7-93, ASCE 7-95, ASCE 7-98, ASCE 7-02 and ASCE 7-05.

This document delineated wind load criteria based on probabilistically determined wind speed and tabulated forms of design load parameters. Determine the external pressure coefficients, Cp, in accordance with ASCE 7 Section 6.5.11.2 or 6.5.11.3. For rigid structures as defined in Section 6.2, the gust-effect factor shall be taken as 0.85 or calculated by a formula.
The first consensus wind load design criteria were published as ANSI A58.1-1972 by the American National Standard Institute (ANSI) in 1972. Determine the gust effect factor G, in accordance with ASCE 7 Section 6.5.8.
