Abstract
Three-dimensional finite element analysis of 1,300 ton stainless water reservoirs was undertaken to consider differential settlement effects of the reservoir when subjected to earthquake loads. The earthquake load for large (>1,000 ton) water reservoirs are further determined using a specification established from the Korean Standards Association. The structural behavior of water reservoirs with differential settlements can be heavily dependent on seismic loading effects. Stress and displacement distributions are induced for various load combinations, including for with and without differential settlements. From numerical examples, the induced maximum displacements of the water reservoirs largely increase with differential settlements compared to those without differential settlements.
