SEAW Commentary on Wind Code Provisions, Volume 1 and Volume 2 - Example Problems

The 2-volume report was developed by the Structural Engineers Association of Washington (SEAW) and edited and published by the Applied Technology Council. (ATC) . Available here as SEAW/ATC-60. (Published 2004; Volume 1: 238 pages, Volume 2: 245 pages)

ABSTRACT: This report presents a practical explanation of the new wind design provisions, methodology to rapidly determine wind forces on buildings and structures, and a rapid visual screening procedure for identifying those buildings that might pose serious risk of loss of life and injury, or of severe curtailment of community services, in case of a damaging earthquake. The screening procedure utilizes a methodology based on a "sidewalk survey" approach that involves identification of the primary structural load-resisting system and its building material, and assignment of a basic structural hazards score and performance modifiers based on the observed building characteristics. Application of the methodology identifies those buildings that are potentially hazardous and should be analyzed in more detail by a professional engineer experienced in seismic design. In the Second Edition, the scoring system has been revised and the Handbook has been shortened and focused to ease its use.
