Abstract

This paper is concerned with an accurate prediction of the effects of adjacent structures on the blast loads on a building in an urban layout. Blast loadings on structures have typically been evaluated using empirical relationships. These relationships assume that there are no obstacles between the charge and the target. In real situations, the actual blast loads can either be reduced due to shadowing by other buildings or can be enhanced due to the presence of other buildings in the vicinity. Results of the numerical simulations presented in this study for a building in an urban environment have demonstrated significant increase in peak pressures and impulses due to the effect of partial confinement. An approach to determining the enhancement factors is described. Keywords: blast loads, urban environment, explosion, nu
