SEISMIC SITE RESPONSE.

Abstract

The site response problem is still a long way from complete resolution. In particular, the one-dimensional body wave solutions, even when fully refined, will not solve the total problem. The engineering approach places undue emphasis on this small aspect of the site response problem to the detriment of attempts to obtain a full understanding of the complete problem. Scepticism is in order over claims to have solved the problems of damage variation using a one-dimensional body wave approach. Such claims must be evaluated carefully for a genuine capability of prediction, rather than mere explanation of a single event. Furthermore, some doubt must be cast by the available evidence on the importance of the local subsoil conditions in affecting surface motion as distinct from damage to structures thereon.
