【 摘 要 】

In case of blast loading on structures, analysis is carried out in twostages, first the blast loading on a particular structure is determinedand second, an evaluation is made for the response of the structure tothis loading. In this paper, a review of the first part is presentedwhich includes various empirical relations available for computation ofblast load in the form of pressure-time function resulting from theexplosion in the air. Different empirical techniques available in theform of charts and equations are reviewed first and then the variousblast wave parameters are computed using these equations. This paper isproviding various blast computation equations, charts, and references ina concise form at a single place and to serve as base for researchersand designers to understand, compare, and then compute the blast waveparameters. Recommendations are presented to choose the best suitabletechnique from the available methods to compute the pressure-timefunction for obtaining structural response.
