【Abstract】 In accord with shearing cantilever beam theory,the vibration equation of the rectangular liquid storage structures with liquid-structure interaction has been established.According to the numerical calculation example of the rectangular liquid-storage structures,the vibration characteristics of those with full liquid have been obtained and compared with the conditions without liquid.The results show that the influence of the liquid dynamic pressure on the vibration frequency can not be ignored and the influence of it on the mode shape is not great.This provides the theoretical basis for the design and calculation of rectangular liquid storage structures.更多还原
