Spectrum Analysis of Isolated Vertical Seismic Response Storage Tanks
Aiming at the problem of seismic response of the base isolation tanks, make the tanks simplify the mechanical model of three particles, considering the quality of continuous liquid that is in the tanks equivalent to convection quality, pulse quality and rigid quality and introducing isolation stiffness. According to the stiffness of each particle and quality calculate natural vibration period, making sure the power amplification coefficient, and analysis on the response spectrum of isolation vertical seismic response storage tanks. The results show that the response spectrum method calculating isolation vertical seismic response storage tanks tends to safety; With the site categories and isolation cycle's increasing, basal shear shock absorption rate gradually reduce, the change of shaking height of wave is not obvious, after isolating the earthquake, hydraulic pressure show linear change, hydraulic pressure increase as the increasing of the site categories and ratio of height to radius, along with the increasing of the isolation of the cycle increasing, hydraulic pressure decrease; ratio of height to radius exists certain optimization period, in the period of optimization, basal shear shock absorption rate is bigger, isolating effect is better.
