Sažetak
The torsional problem of a pontoon, consisting of channel middle part and rectangular tube peaks, is considered within the higher-order beam theory. The cross section and the contour capability conditions for assembling of the pontoon parts are investigated. The acceptability of the introduced assumptions is checked by three-dimensional finite-element model analysis. Some deficiencies of the classical beam theory regarding the girder stiffness are noticed. The finite-element formulation to be used for torsional analysis of the ship's hull with large hatch openings is given.
