Earthquake Direction Effects on Seismic Performance of Concrete Gravity Dams to Mainshock–Aftershock Sequences
The aim of the present study was to examine the effects of earthquake direction on seismic performance of concrete gravity dams subjected to seismic sequences. For these purposes, two seismic incident directions are applied along horizontal axes to assess the maximum structural demands. Nonlinear dynamic analyses of the dam-reservoir-foundation system subjected to as-recorded mainshock–aftershock sequences are conducted to investigate the effects: 1) direction of single earthquake events; 2) direction of seismic sequences; 3) aftershock polarity; and 4) earthquake intensity. The results indicate that earthquake direction can significantly change the damage propagation processes of concrete gravity dams.
