Abstract :
The dynamic behavior of a very large rectangular floating structure is
considered. The structure is modelled as a plate with free edges. Two different
thicknesses are considered for the model. The Mindlin plate theory is used to
formulate the structure behavior. Natural frequencies, mode shapes, and stress
resultants of the structure are predicted by using finite element method. For this
purpose, a MATLAB code is written. The same analysis is performed by using
the ANSYS software. The results of these two analysis are compared with each
other and with the available results in the literature, where close agreement is
observed. Therefore, the written finite element code is found to be acceptable
for prediction of the dynamic behavior of very large rectangular floating
structures in early stages of design.
