Abstract
The thesis starts by giving a background introduction about the
ingredients and characteristics of the chemical explosives and the
behaviour of the output gass pressures or seismic vibrations . The
factors affecting the transmision of these outpu~ are illustrated either
the explosion is in air, underground, or underwater. Also, the thesis
presents some of the previous theoretical models for simulating the
explosion load and denoting the procedures for these methods to
calculate all characteristics of this load . The thesis presents an
experimental work which was carried out by the researcher in different
locations to record the dynamic load output from some explosions by
using special measuring instruments at different distances from the
explosion source . A discussion of these experimental results compared
with the theoretical models results (including analytical study for all
parameters affecting the loading behaviour) is presented. Some
numerical applications to calculate the structures response due to
explosions are illustrated using the available theoretical models through
a computer program written in fortran language to simulate the dynamic
response of stuctural elements . Finally , the thesis conclusions are
presented.
