The objective of this paper is to clarify dynamic response behavior of RC columns under water. The dynamic reversed cyclic loading test of RC column specimens has been conducted. The specimen in water subjected to lateral loads with dispalcement rate of 500mm/sec exhibited lower ductility than the specimen in air. This might be due to the internal water pressure in carcks together with the loss of friction and interlocking. Dynamic water pressure induced by crack opening-closing was also examined by conducting dynamic loading test as well as numerical calculation using SPH method.
