Abstract
Currently in Ukraine the production of wooden I-beams with a wall of OSB is a steady increase. Analysis of the structural forms of composite beams, the features of their use in the frame of buildings, along with the existing methods of the composite wooden beams calculating, indicate that, if certain requirements are met for wooden I-beams, they can be used in polygonal vaulted coverings span of 12-18 m. Polygonal shape of the coating is made possible by special steel connecting elements. During the design, various solutions of the nodes (hinged, flexible, and rigid) were considered. Based on the preliminary calculations, hinge nodes were selected. The considered constructions are made of wooden I-beams with OSB-wall next sizes: beam height 120 mm, belt height 40 mm, belt width 90 mm, thickness of OSB wall 10 mm, length 1400 mm and more, connected by pairs of metal pads. Calculations of the structures with a span of 12 and 18 meters and an analysis of their stress-strain state are given.
