Investigating Seismic Response of Container Crane Subjected to Near-Field Ground Motions

In this paper, the seismic response of a container crane subjected to near-field ground motion was studied via using a shake table testing on a 1/20 scale container crane. The 1/20 scale model was designed and manufactured based on the theory of similitude laws. Three independent quantities as geometric length, acceleration, and elastic modulus were selected as fundamental parameters to design the 1/20 scale model. Two near-field ground motions were chosen as input ground motions to investigate the seismic response of the 1/20 scale container crane at the Seismic Research and Test Center, Pusan National University, Yangsan Campus. The results show that the maximum moment occurs on the location of the top of the lower seaside leg.
