Effects of safety factors on the deflections in a concrete gravity dam

摘要

The aim of this study was to determine the effects of safety factors on the deflections of a concrete gravity dam. Overturning and sliding safety factors for a selected concrete gravity dam with base width b and height H were specified, using pseudo analysis for the b/H ratios and earthquake acceleration values between 0.1 g and 0.4 g. Deflection values for specified parameters were obtained from the structural analysis program SAP2000. Deflection safety factor curves, determined from the b/H ratios, were obtained, as well as the earthquake acceleration values. The results of this analysis showed that safety factors reduced while strain values increased.
