Abstract

To evaluate the dynamic behavior of a container crane under seismic loads accurately, the contact state between the wheels and the rails or the ground that significantly affect the seismic response of the structure must be considered elaborately. This paper proposes a modeling method based on the theory of contact and friction for simulating the nonlinear seismic response of large and flexible structure for a jumbo movable container crane, including the contact problem regarding the wheels attached to the bottom of its legs and the rails on which they ride. These models are used to perform extensive dynamic time-history analysis in order to find out their nonlinear dynamic behavior under various excitation modes. It is found that the presented numerical modeling method simulates the nonlinear seismic response of a container crane quite well. Notably, it can verify and expand our understanding of the seismic behaviors by evaluating response performance for other large seaport cranes.
