Buckling may be occurred on thin wall vessels under excessive seismic loads. It is valuable for failure consequence mitigation to clarifypost-buckling behavior. In order to clarify response behaviors with buckling under dynamic loads, authors conducted shaking table tests of beams which is simple structure.
