A CONSIDERATION ON THE DYNAMIC BEHAVIOUR AND THE STRUCTURAL DESIGN OF LARGE SCALE FLOATING STRUCTURES

This paper presents a simplified analysis of the dynamic behaviour of a large floating structure as a working model for the decision making model in the structural design and the design of the structure is also discussed. The model of the structure in the analysis is a beam of finite length on an elastic foundation with damping. This modelling is the most simple but is satisfactorily accurate to address the global behaviour of the structure. An analytical solution of this model is derived and from the discussion, it is shown that the range of natural frequencies are higher than the heave natural frequencies. The quasi-static solution is compared with the dynamic calculations. At lower frequency, static solution gives relatively accurate prediction for the deflection and stress of the structure. With the analyses, design philosophy of the structure is discussed mainly from the view point of resonance avoidance design and selection of structural parameters.
