The author has performed comparative calculations for restrained struts based on approximate solutions of differential equations of deflection curve by the strength of materials formula and the recommended formula in Building Regulations. Such calculations are needed due to new engineering developments providing rigid fixing for the ends of wooden components. The calculation theory of compressedbent and eccentrically compressed bars using strength of materials equations involves the use of the formulae both at the elastic stage and beyond. At the same time, the edgestress calculation is complicated by the influence of deformations and the need to use variable modulus of elasticity. The author shows that the calculation by standards can be simplified by introducing a constant modulus of elasticity for the limit states of the second group (10,000 MPa) and to calculate the limit states of the first group, reduced to 4500 MPa. The formula can be applied within the entire load range. The author has determined the validity range of the calculation for eccentrically compressed struts by the formula adopted in the Building Regulations for stability analysis of central struts.Authors
