Container Crane Seismic Isolation Device Design Method Based on Structural Dynamics

Article Preview

Abstract:

Based on container cranes seismic load calculation criteria with structural dynamics and damage modes of container crane under earthquake, the seismic isolation device of this over-span flexible structure and its associated parameters selection were investigated. Taking the first crane equipped with isolating device as an example, through dynamic analysis and simulating to crane flexible system with isolation device under the earthquake, efforts was made to research for suitable isolation device and design method for port crane. The calculation and analysis in the present study could provide a new way for the container cranes isolation device design and assessment of the structural anti-seismic effect
