Existing methods for calculating the width of cracks in reinforced concrete elements do not take into account the spacing of stirrups and rods welded mesh. Bars weaken the cross-section of element, followed by concentration of stress, and thus the chances of cracks in a place to increase. To examine this relationship has been made and tested in bending 12 reinforced concrete slabs with different spans of transverse rods and 16 stretching slabs. The results present that a grid spacing of transverse reinforcing rods directly affects the step width of cracks and their disclosure in the reinforced concrete elements. Now is prepared a computer program to model the formation of cracks in reinforced concrete elements, reinforced by stirrups and meshes of rods with different spacing of transverse bars.
