There are many different types of wharf constructed, i.e. Caisson type, sheet pile wall type and pier type. The natural period ratio between a pier type wharf and a crane is rather close to 1.0. Also the weight ratio between a pier type wharf and a crane is around 0.5 or higher. The behavior of container crane and pier type wharf during earthquake is affected by the interaction each other. Therefore, in this paper, to investigate the effect of the interaction between the container crane and pier type wharf, we carried out an excitation test on a 1/15 reduced scale test model of a container crane and a pier type wharf. And we proposed a simple double decked mass-spring model, The numerical simulation results showed good agreement with the shaking table excitation test results.
