This article describes a method for building the influence line of bending moments in statically indeterminate 2d frame using SCAD software. The result is compared with the bending moment diagram obtained in SCAD software. Then there is an analysis of the convergence of the calculation results. Authors made a conclusion about the appropriateness of the method. This article describes a method for constructing the influence line of bending moments in statically indeterminate plane frame using SCAD software. The method consists in the construction of the settlement scheme in SCAD software and collecting the values of displacements to formula. The result of applying the formula given in the article is the influence line for the bending moments of the moving load. The resulting influence line is compared with the bending moment diagram obtained in PC SCAD.
