Abstract
Hydroelastic behavior of a flexible floating structure supported by several aircushions arranged in a lattice is discussed in this paper. The modified pressure distribution method, which can consider influence of the aircushion, is applied to a prediction of the hydrodynamic forces.
A general pontoon type and four aircushion models are used for the prediction of elastic behavior. From the results, it is possible to reduce the response even if unit aircushion is a small scale. And also the aircushion type is useful to reduce the response of the structure in oblique waves.
