Paper deals with a new constructive solution of a massive concrete pillar intended, mostly, for construction of railway and road bridge supports and with procedure of rationalization of its parameters. Statement and solution of the problem of strength and stability of a concrete support, which has an external mesh cage, reinforcing rings (frames) and an internal cavity is considered. The contact stresses between the concrete core and the metal cage are determined, which, in turn, depend on the attributes of the cage and the frames. The rationalization criterion based on minimizing the potential energy of deformation is introduced. For the indicated task, the variables are the thickness of the mesh cage, the size of its cell, the step and the cross-section of the frames. Support with rational parameters which depend on characteristics of cage and frames gives the lowest material consumption and the highest bearing capacity that is the aim of the approach of investigation.
