Abstract
Abstract
The article presents a new design of a wooden beam. The essence of the proposed design is the rational reinforcement of multi-span glued beams. Reinforcement is performed in places of stretching of wood fibers according to the diagram of moments. A comparison of the design to assess its rationality was made with an unreinforced glued beam with the same design scheme. The numerical experiment showed the relevance of such amplification. So at the same given load there is a significant reduction of normal and tangential stresses in the cross section of the structure under study, which ultimately leads to a reduction in the cross sections of the whole beam and its better ergonomics. From the point of view of work production the technology on pasting of cores in a beam body can be considered well approved positively affecting technical and economic indicators.
