Abstract: Anti-seismic analysis of a large annular lifting equipment is carried out under considering the influence of local dynamic effect and the change of system acceleration table value at different elevations, and the calculating formulas of the seismic action and the seismic response at 42.5 m height of elevation in the equipment are deducted. The related calculating procedure is worked out. The local dynamic effect and the influence of change of acceleration spectrum value through analysis and calculation to practical equipment are minutely investigated. These are beneficial to engineering design.

Key words: Acceleration spectrum value, Annular lifting equipment, Local dynamic effect, Seismic combination
