Design Charts for Cold-Formed Steel Panels and Wide-Flange Beams Subjected to Blast Loads.

摘要

The report presents design charts for the selection of cold-formed steel panel and wide-flange beam sections used in structures designed to resist blast loads produced by high-explosive detonations. These steel sections are applicable to the walls, roof, and supporting members (girts, purlins, etc.) of blast-protective acceptor structures in Army Ammunition Plants and other explosive manufacturing and storage facilities. Each design chart consists of plots of steel panel or beam sections versus triangular pressure pulse, for a particular post-accident usability, span length, support condition (applicable to single and multiple spans) and beam spacing. Pressure levels up to 12 psi and pulse durations from 20 to 400 ms are covered by the charts. Illustrative examples are included.
