Strong-motion instrumentation of concrete dams G.R. Darbre Swiss Division of Safety of Dams, P.O. Box 2743, CH-3001 Berne, Switzerland INTRODUCTION Background and objectives The validity of the excitations and of the models of analysis used in the assessment of the earthquake behavior of structures can only be checked by way of comparison with field observations. The latter are at the present time incomplete and there is a need for field measurements during earthquakes in general and for strong-motion instrumentation in particular. The measure- ments may be associated with free-field observations from which informati- ons on earthquake characteristics (including wave-propagation aspects) and recurrence at specific sites can be obtained, and with structural observations from which specific aspects of the earthquake behavior of different types of structures can be studied (high-rise buildings, industrial facilities, nuclear power plants, bridges, dams,...). The aim of
