Abstract

The method of designing reinforced wooden beams of variable stiffness with group reinforcement is described. The dependence of the breakage of reinforcement in the span on the reinforcement coefficient is given and the influence of changes in the stiffness of structures on the deformability is determined. Theoretical stress diagrams are analyzed, indicating the possibility of hazardous stress concentrations in reinforced beams of variable stiffness. Diagrams M and Q, as well as schemes of theoretical breakage of reinforcement in beams were constructed. The results of determining the influence of the reinforcement coefficient on the place of breakage of reinforcement in the span of beams are displayed graphically. The dependences of the anchorage length on the diameter and reinforcement coefficient, the relative length of the anchorage of the rods on the span of the reinforced beams have been constructed. Defined deflection of reinforced wooden beams of variable stiffness. A further direction of research is indicated, which consists in determining local stresses in zones of change in the stiffness of beams.
