As the new Eurocode 8 on the Design of Structures for Earthquake Resistance has acquired the status of a full Euronorm, practical information and training has become urgently needed, especially in relation to the underlying principles of seismic behaviour and the design of building structures. This book covers seismic design in a clear but brief manner and links the principles to the code, illustrated with design examples. Concrete and steel buildings, and their foundations, are given special emphasis but the book is also applicable to many other types of structure and sub-structure.The book stems from practical short courses on seismic design, run jointly by the Society for Earthquake and Civil Engineering Dynamics (SECED) and Imperial College London. Its contributors are either senior academics with significant consulting experience, or leading practitioners, which gives the book a strong industry emphasis. It will be of value to a wide range of practising civil and structural engineers at different stages of their careers; and should also be of direct use to academics preparing courses and worked examples on seismic design to EC8, to advanced undergraduate students, and to Masters level students in Earthquake, Structural or Geotechnical Engineering.
