Seismic Behavior Considerations for Jumbo Container Cranes
This study aims to qualitatively describe the seismic behavior of container cranes. Due to the nature of container crane construction, the portal frame in a crane is highlighted as the controlling aspect for seismic performance. Notably, the effects of the portal frame structural response and the uplift/rocking response are considered in depth. A detailed finite element model is used to consider a case-study container crane to verify and expand our understanding of the seismic behavior. It is found that the coupling between portal frame response and rocking is critical, especially when evaluating performance nearing ultimate. There is a narrow margin between first yielding and potential structural collapse. Several general strategies are proposed to design safer, more resilient cranes in the future.
