Abstract

Abstract

The hydrodynamic pressure induced by earthquake to the cylindrical structure in extreme shallow water is studied.The earthquake hydrodynamic pressure for the cylindrical structure may approximately be calculated by the chopras formula for the rectilinear wall when the ratio of external water depth to the cylinder radius is smaller than 0.3.The effects of elastically hydrodynamic pressure can be ignored if water depth is smaller than half height of the structure in engineering.The simplified formula for calculating earthquake-induced hydrodynamic to cylindrical structure in extreme shallow water is suggested.
- Hydrodynamic pressure,
- artificial island,
- fictitious apparent mass,
- coefficient of curvature effects
