ANALYSIS OF STRUCTURAL SOLUTIONS OF BEARING RIBS OF LARGE-SIZED COMBINED PANELS ON A WOODEN FRAME

Large-sized combined panels on a wooden frame are widely used in domestic and foreign construction practice, combining all the well-known advantages of wood as a building material. The effectiveness of their application is achieved by combining load-bearing and enclosing functions, when the main load-bearing ribs work together with the sheaths when exter-nal operational loads are perceived. It is most advisable to use large-sized panels as “span-by-span” structures with their support directly on longitu-dinal load-bearing walls or substructure elements. At the same time, the main disadvantages of known design solutions include either significant material consumption or high complexity of manufacturing. As a rule, the noted disadvantages relate to the structures of the main load-bearing ribs. The article presents a thorough examination of the established design solutions for large-sized combined panels on a wooden frame, taking into account the incorporation of sheaths in the overall design of the structure. Both their advantages and disadvantages are reflected. Taking into account the results of the analysis, ways to improve the structures of the main ribs are proposed, the implementation of which ensures a reduction in material consumption and ease of manufacture of the considered class of panels while maintaining their strength and stiffness.
