The container crane received large damage in the 1995 Hyogoken-Nanbu earthquake. In order to confirm the behavior of the container crane, the shaking table tests were carried out by using 1/15 scale model. Two kinds of states of the crane were examined. One was the state of the boom down (working) and another one was the state of the boom up (resting). The rocking with uplifting of legs of container cranes was observed in the state of the boom down, and was not in the state of boom up. Therefore, the bending moment at the damaged member in the state of the boom down was 1.25 times the bending moment in the state of the boom up. The numerical analysis simulation result showed the experiment result and a good agreement including the residual stress.
