Extreme Wind Design of Self-Supported Steel Structures: Critical Review of Related ASCE Publications
Publication: Practice Periodical on Structural Design and Construction
Volume 8, Issue 2
Abstract
Depending on the application, self-supported tubular steel pole (cantilever) structures in the United States are designed for extreme wind loadings based on either ASCE 74 (for electric utility applications), ANSI/TIA/EIA 222 (for antenna applications), AASHTO (for highway sign and traffic signal applications), or ASCE 7 (for general applications, such as stadium billboards). This paper compares the margins of safety of self-supported tubular steel structures designed for extreme wind loadings based on ASCE 74, TIA/EIA, AASHTO and ASCE 7. Based on this comparison, a critical review of the ASCE publications and their respective design requirements and safety factors are presented.
