Calculation Methodology for Constituent Wooden Rods on Discrete Shear Bonds
Almost all methods for calculating constituent rods are based, as a rule, on a uniform, rather frequent arrangement of shear bonds along the length of the bar. Calculations based on the solution of differential equations, even for simple cases of a symmetrical section without taking into account the vertical stiffness of the bonds, turn out to be rather complicated. Approximate calculations obtain good convergence also only in the case of a sufficiently large number of connections. The proposed work presents a fairly simple approach to the calculation of composite bending rods on discrete shear bonds. The technique makes it possible to take into account the nonlinear dependence of deformations on the forces in the bonds; take into account the positions of shear forces in the bonds along the height of the beam cross section, which leads to a significant increase in the accuracy of calculations. Additional features of the technique include: taking into account the transverse stiffness of the bonds; the possibility of calculating with different stiffness of the elements that make up the rod; the possibility of taking into account an arbitrary arrangement of discrete bonds along the length of the beam, depending on the type of loading. As a result, according to the proposed method, on the basis of numerical analysis, an assessment was made of the significance concerning these factors in the calculations of bending constituent rods.
