Abstract:

In recent years, the explosive devices have become major weapons of choice of the most of the terrorist attacks. Such factors, as easy accessibility if information on the construction of the bomb devices, relative ease of manufacturing, mobility and portability, coupled with significant property damages and injuries, are responsible for significant increase of bomb attacks in all over the world. In of most cases, structural damage and the glass hazard have been major contributors to death and injury of the targeted buildings. While the issue of blast-hardening of structure has been an active topic with the military services, the relevant design documents are restricted to official use only. A very limited body of design documentation currently exists which can provide engineers with the technical data necessary to design civil structures for enhanced physical security. The professional skills required to provide blast resistant consulting services include structural dynamics, knowledge of physical properties of explosive detonations and knowledge of physical security practices. In this study, damaging ways from a bomb explosion, mitigation of blast effects and protective design for a bomb blast was investigated. A blast modelling software (AT Blast) was used for the evaluation of blasting effects and SAP 2000 software was used for the evaluation of loading effects.

Keywords:
