This report, in six volumes, details design procedures for structures which are subjected to the effects of accidental explosions. The procedures cover the determination of the blast environment (blast and fragments) and then structural design. This volume, Principles of Dynamic Analysis, in particular, contains the procedures for analyzing structural elements subject to blast overpressures. It discusses the basic principles of dynamics as well as procedures for calculating the various components used to perform the analyses. Also presented are resistance-deflection functions for various elements including both one- and two-way panels as well as beam elements. These functions include the elastic, elasto-plastic, and plastic ranges of response. In addition, a discussion of dynamic equivalent systems (single- and multi-degree-of-freedom systems) is presented. A step-by-step numerical integration of an element's motion under dynamic loads using the acceleration-impulse-extrapolation method or the average acceleration method and design charts for simplified loads is illustrated. It also includes methods for analyzing elements subjected to impulse type loadings, that is, loadings whose durations are short in comparison to the time to reach maximum response of the elements. Example problems and solutions using these procedures are also included.
