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