Section on application of the inelastic design spectrum to structural design – For allowable ductility, seismic evaluation of existing structures, and displacement-based structural design. Examples on dynamics of bridges and their earthquake response. Incorporation of three building codes and inclusion of the Eurocode. Theory of dynamic response of structures – Presented in a manner that emphasises physical insight into the analytical procedures. Structural dynamics theory – Applied to conduct parametric studies that bring out several fundamental issues in the earthquake response and design of multistory buildings. Analytical procedures – Illustrated by over 100 worked out examples. Over 400 figures carefully designed and executed to be pedagogically effective.  Photographs of structures and their responses recorded during earthquakes – Included to relate the presentation to the real world.
