Round timber with core rot was not used in the production of sawn timber for load-bearing building structures. The purpose of this work is the researches of a possibility of receiving wooden beams from round timber with a core rot. The wooden I-beam made of angular elements of the received their round forest products with decay was chosen as the object being studied. The design scheme for determining strength and deflections of the beam is a statically determinate hinged beam, loaded with a uniformly distributed load. The design spacing of the structure is assumed to be 6 meters. Under the action of a load equal to 1.5 kN/m, the beam is exposed to stress-strain state of transverse bending. A method for manufacturing I-beams from corner elements obtained as a result of cutting round logs with core rot is proposed. It has established that the calculated strength characteristics of I-beams produced according to the proposed technology may resist operational loads. Rated and tangential stresses arising from application of loads do not exceed the permissible values. Deflection of a beam does not exceed allowable deflection values. The use of round timber with core rot increases resources of wood for construction.
