Container cranes seismic load calculation criteria based on structural dynamics

Based on damage modes of container cranes under earthquake and theory of structural dynamics, response spectra of seismic load is the most popular frequency domain method to get maximal response acceleration of structure. On the time domain, the finite element dynamic time-history is the main way. According to the dual criteria of structure by earthquake and applied range of these two analytical methods, a new analysis procedures of container crane seismic load based on structural dynamics is be created. In order to test veracity and reliability of this procedure. Six main type cranes are applied on. The calculation and analysis in the present study could provide the data base and design parameter for the anti-seismic design on next step.
