In the article it is reflected the results of carrying out numerical research of supporting capacity of side interfenestral bus body pillars. It is carried out calculating of detailed final element model of bus body pillars with considering the physical and geometric nonlinearity. The implementation of final element analysis of the stress-strain state of bus body pillars is provided for simple and complex bending. It is made the consideration of the influence of chemical material corrosion on stiffness and strength characteristics of the body pillar. Modeling is made with the use of opportunities of a package of the applied ANSYS programs.
