THE STRUCTURAL BEHAVIOUR OF A HUGE PONTOON-TYPE STRUCTURE UNDER DYNAMIC LOADS

Huge floating structures such as floating airports are relatively thin in comparison to their plane areas. Most research carried out on the structural behaviour of such structures under dynamic loads were on structures with footings and not pontoon-type structures which are more fundamental in shape. The paper summarises Toki's (1979) solution in a more comprehensible form with due correction of minor mistakes. The formula is applied to a pontoon-type floating structure. The structure was replaced with an equivalent rectangular flat plate to apply the finite element method. The modes and natural circular frequencies obtained were compared with those of a beam analysis.
