This report details design procedures for structures which are subjected to the effects of accidental explosions. The procedures cover the determination of the blast environment and structural design. This volume contains procedures and guidelines for the design of blast resistant steel structures and elements. Light construction, steel framed acceptor structures provide an adequate form of protection in a pressure range of 10 psi or less. However, if fragments are present, light gage construction may only be partially appropriate. Use of structural steel frames in combination with precast concrete roof and wall panels Volume VI will provide a measure of fragment protection at lower pressure ranges. Containment structures, or steel elements of containment structures, such as blast doors, ventilation closures, fragment shields, etc. can be designed for almost any pressure range. This volume covers detailed procedures and design techniques for the blast resistant design of steel elements and structures subjected to short duration, high intensity blast loading. Provisions for inelastic, blast resistant design will be consistent with conventional static plastic design procedures. Steel elements such as beams, beam columns, open web joints, plates and cold formed steel panels are considered. In addition, the design of steel structures such as rigid frames, and braced frames are presented as they relate to blast resistant design. Special considerations for blast doors, penetration of fragments into steel and unsymmetrical bending are also presented.
