ANALYSIS OF THE SEISMIC BEHAVIOR OF KEDDARA DAM USING STRONG MOTION RECORDS

摘要：

On May 21, 2003 the Keddara rockfill dam was shaken by Boumerdes earthquake (ML=6.8) which epicenter was located at 20 km from the dam. Accelerographs, installed on the crest and the right abutment by the Algerian National Centre of Applied Research in Earthquake Engineering, have measured the motion during the main shock. Nonlinearities may have affected the behavior of the dam during this event. In this study, we provide an analysis of what took place during the main shock, and on the basis of the strong motion records, we investigate the possible development of nonlinearities in the dam materials and the importance of loss coherency effects.
