In the paper there is considered a study of stress-strain state of a rectangular wall panel with an opening for a window aperture (Figure 1). The design scheme of a real wall panel is represented in the form of a hinge-supported at the ends, stepwise-variable-thickness rod. Similar designs are also used in mechanical engineering as metal parts with an opening. The design of such a rod is performed for a vertical concentrated load Px (weight of the overlying wall panels of 2-5 floors) and for the effect of various loads in the form of a uniformly distributed transverse pressure qy. The opening for the window aperture is accounted through the moments of inertia of the rod parts cross sections that are given along the length of the rod. As a result of the calculations performed along the length of the stepwise-variable rod, there have been obtained ordinates of the transverse and angular displacements, axial displacements, internal transverse and longitudinal forces, and the corresponding diagrams of the force and strain factors have been plotted according to their values.
