Abstract
The research compares precise, strength-defining characteristics, geometrical parameters of cross-section of the deformed frame beam’s web and the frame beam with a hull strake attached for a deformed web with several models that successively replace the original section. The models have several options for the ratio of the height of the web to its thickness and different forms of buckling of the beam web. In addition, it is demonstrated that the precision of modeling makes it possible to satisfactorily assess the geometric parameters of the strength of the cross-section of the frame beams of the ship's set with a deformed web without direct access to the beam and evaluate the zone and type of web strain by measuring the deformation of the outer sheathing at the point where beam is attached. A composite model is recommended as the main one, representing a combination of a simulated undeformed T-beam with a web of the same thickness, depth, which is equal to the that of the web of the deformed beam, and plating onto the plane of the beam web adjacent to the casing. It is concluded that the use of the above-mentioned simulation method makes it possible to obtain an analytical description of the geometric parameters for strength of a model with satisfactory accuracy.
