WATER EFFECTS ON HYSTERESIS CURVE WITH SEISMIC SOIL-STRUCTUREINTERACTION

Hysteresis curve during earthquakes is affected by nonlinear Soil-Structure-Interaction (SSI). Regard to water can have a change result of soil, the effect of water on SSIfor the marine structures is the fascinating subject. In present paper, the Hysteresis curve of pile with superstructure is investigated by comparing with saturated soil and dried one. For these goals, analyses of a single pile in cohesive soil with nonlinear pier to ground motion have been performed and the consequences in Hysteresis curvehave been exhibited. This complex system has been produced using Open System for Earthquake Engineering Simulation (OPENSEES) Software. By comparison to Soil-Structure-Water-Interaction, structure analysis parameters are changed by considering water.
