This book provides a general introduction to the topic of buildings forresistance to the effects of abnormal loadings. The structural designrequirements for nuclear facilities are very unique. In no other structural systemare extreme loads such as tornadoes, missile and loud interaction, earthquakeeffects typical in excess of any recorded historical data at a site, and postulatedsystem accident at very low probability range explicitly, considered in design.It covers the whole spectrum of extreme load which has to beconsidered in the structural design of nuclear facilities and reactor buildings,the safety criteria, the structural design, the analysis of containment. Test casestudies are given in a comprehensive treatment.Each major section contains a full explanation which allows the book to be usedby students and practicing engineers, particularly those facing formidable taskof having to design complicated building structures with unusual boundaryconditions.
