STRENGTH AND RELIABILITY OF OPEN CROSS-SECTIONS THIN WALL BEAMS IN A RAFT LOAD-BEARING STRUCTURE
Abstract
The aim of this paper is to present the application of thin-walled beams on cargo raft load-bearing structure from the aspect of strength and reliability. The beams have an open cross section. Analytical and numerical determination of equivalent stresses and deformations of open section thin-walled ‘U’ and ‘Z’ cantilever beams, loaded with torsion, is presented. Work is divided into three parts. In the first part, equivalent stress and deformation are obtained analytically for cantilever beam model in the whole cross section. In the second part, the finite element method is applied in beam models, and the results are compared with the analytical calculation. The third part presents the profiles installed in load-bearing structures of vessels (rafts) and solutions are shown to apply results of the presented analyses in order to increase reliability. Finally, the design calculation of the raft load-bearing structure is shown.
