This book is the expanded version of the earlier (first edition) text. It presents new comprehensive rational quantitative theories (utilizing fundamental energy concepts throughout) covering the entire earthquake event from the point of view of the engineer. It starts with a mathematical analysis of an underground mechanism (the earthquake), then proceeds to determinations of the timewise and spacewise variations of the fundamental engineering damage-design parameter, the ground energy. Finally, the new theories are applied to a number of typical (actual) structural and non-structural design problems. Each chapter of the first edition has now been improved and enlarged and new chapters have been added to include recent research by the author and his graduate students.
