Modelling of blast and fragment loading effect

This thesis aims to study the influence of distance on the effects of blast loading towards the structural integrity of a building. Growing global apprehension about the malicious fangs of terrorism has forced the hands of many countries to anatomise their existing security measures. A compact city...
