Abstract

The paper deals with the analysis of structure subjected to the blast load created by the explosion of ANFO explosives (ammonium nitrate and fuel oil). The paper presents the influence of blast wave idealisation on dynamical analysis of structure. Steel beam is loaded by different blast load model representing different ways of approximation of blast wave created after the explosion of explosive substances. The shape of blast pressure wave is idealised by three basic shapes – with linear decay time profile, exponential decay time profile, and exponential decay time profile considering negative phase. Dynamical analysis is done and the results from structures loaded by idealized profiles are compared with the experimental obtained results from the field test.
