LIMITATIONS ON THE APPLICATION OF EFFECTIVE BREADTH CONCEPT IN BOX GIRDER DESIGN

Analysis of the upper hulls of a semisubmersible drilling platform by finite element approach shows that the conventional effective breadth method for box girder design has serious limitations when applied to the modern drilling vessels where complicated structural geometry and unusual loadings are often encountered. In some cases, it is recommended to vary the thickness across the flange according to the actual stress distribution which can be found by modern computing techniques.
