From the developer:
SBEDS is an Excel© based tool for the design and analysis of structural components subjected to dynamic loads, such as airblast from explosives, using single-degree-of-freedom (SDOF) methodology. SBEDS is based on Army TM 5-1300 (also designated as NAVFAC P-397 and AFR 88-22) and UFC 3-340-01, but draws on other sources where improved methodologies are available.
