The article considers issues of industrial buildings frames strengthening by the introduction of stiffening elements at the change of calculated seismicity. The principle of materials concentration in the form of stiffness elements with included connections is used. The degree of their influence on the work of building frame is estimated. In this case, the work of coating disk as an element distributing horizontal forces changes. The main dependencies for gap definition determined by the reinforced concrete frame movements, at which moments in the lower section of the columns reach the limit values, are determined. Thus, in the process of influence the seismic force will remain approximately constant, as the total stiffness will be slightly higher than the initial columns stiffness. Introduction of rigidity elements into the frame should be accompanied by corresponding measures for strengthening of foundations for steel supports.
