PREFACE In structural engineering, one of the constant challenges is to find new and better means of designing new structures or strengthening existing ones so that they, together with their occupants and contents, can be better protected from the damaging effects of destructive environmental forces such as wind, wave loads, and earthquakes. As a result, new and innovative concepts of structural protection have been advanced and are at various stages of development. Structural protective systems can be divided into three groups as shown in Table I. The technique of seismic isolation is now widely used in many parts of the world. A seismic isolation system is typically placed at the foundation of a structure which, by means of its flexibility and energy absorption capability, partially absorbs and partially reflects some of the earthquake input energy before it is transmitted to the structure. The net effect is a reduction of energy dissipation demand on the structural system, resulting in an increase in its survivability.
