SLIDING ANALYSIS OF A SOFTLY INSTALLED MARINE STRUCTURE WITH LIQUID STORAGE TANKS DUE TO EARTHQUAKE
|
�´˜^�i‰p�j�F
Numerical sliding simulation method of a softly installed marine structure with liquid storage tanks has been developed considering the coupled interaction between the rigid structure swaying motion and the hydrodynamic sloshing motion of inner fluid. Our proposed model was verified through comparing with Nakayama's fluid sloshing model without sliding motion. We investigated the effects of fluid hydrodynamic interaction on the sliding behavior of the softly installed marine structure through our proposed sliding model as well as a simplified fluid vibration model given by Housner.
