Such events have generated cons- erable concern over the ability of countries and governments to protect - stallations and their occupants against a potential threat of terrorism. Many countries have established defence agencies and research councils who are currently examining the structural integrity of existing buildings and other vital installations. In some countries codi?ed methods have been developed together with the design methodologies and construction techniques to try to protect old installations against vehicle bomb e?ects in particular. The purpose of this book is to give an exhaustive study of buildings structures resistingexplosion with and withoutexternal/internalimpactand ?recaused by such e?ects.
