Some features of a graphic presentation of rod/beam constructions strength analysis results obtained with the help of ANSYS finite element program are shown in the article in the form of test examples. It is noted that the results graphic presentation that ANSYS generates is influenced not only by the spread loads application mode and the settings used for this presentation (the absolute value and the scale factor sign), but by the order of joining the keypoints when making-up the rod/beam axis as well as the usage of Boolean operations when creating a geometric model. The explanations as to the filling in the SHEAR field when making up in the ANSYS system the beam models based on the elements that don’t take into account the influence of the shear on deflection are given in the article. In this field, for short beams, the value of the factor that enters into the differential equation of an elastic line and taking into account the tangential stress non-uniform distribution with the height of a cross-section at transverse bending and that appears in a differential equation of the deflection curve is given.In the article, values of this factor for box section beams as a function of its sides length ratio as well as for beams of normal and wide I-beams are given. The reference information available in ANSYS Help that is necessary to present the results in table or graphical forms is represented in the form adapted for direct application. The sequences of commands to form the tables and the graphs are available in the article as well
