Using a beam model capable of f l ~ a l and torsional deformations, the mode shapes and frequency eq~tions are presented.~ An analysis is carried out for the Foothill Boulevard Undercrossir~, S.E. Bridge in the San Fernamdo Valley, California which suffered d~m~ge to the intermediate supports. The results of the analysis correlate well with the observed damage pattern of the bridge.

The time wriation of amplltmde and frequency content is preserved in the simulation procedure. Sixteen artificial earthquake accelerograms are simulated and compared with a target accelerogr~. The time variation of amplitude and frequency content for 26 hlstoric~l earthquake accelerograms is characterized. Auth.

A general procedure for analysis of the response of ~ avity dams, including hydrodynamic interaction and compressibility of water, to the transverse horizontal ~n~ vertical components of earthquake ground motion s presented. The problem is reduced to one in two C~imensions considering the transverse vibration of a monolith of a dam, a~d the material behavlour is assumed to be linearly elastic; The complete system is considered as composed of two substructures-the dam, represented as a finite element system, and the reservoir, as a continuum of infinite length in the upstream direction governed by the wave equation. An example analysis is presented to illustrate results obtained from this method. It is concluded that the method is very effective stud e~iclent and is capable of producing results to any desired degree of accuracy by including the necessary nsmber of models of vibration of the dam.

Report number NRC-DES 72-1.3F,1T, Refs. NAT. TEC~. INFORM. S~RV. FB- 208.327,1972, 29P. Earthquakes have been observed during amd after filling of some large man-made reservoirs, although others, equally large s have been earthquake-free. Some of those observed, in other countries, have caused loss of life and significant damage: The report m~msrizes the history of recorded cc~relations, discusses the scientific considerations, ard makes reco~enlations designed to iml~ove our umd~standing of the problem. The recommendations concern specific geologic, and seismic studies --before, durlmg, and after the filling of large reservoirs -- that can provide the required information. Auth.
