Experimental studies of short reinforced concrete beams with flight of a cut of a/h0 to 1.5 are given. The program of researches provided: definition of influence of flight of a cut on the character of cracks formation, a type of destruction in beams without cross fittings and in the beams reinforced by evenly distributed fittings; definition of influence of the horizontal and vertical distributed fittings on durability, crack resistance and width of disclosure of cracks. On the results of researches schemes of destruction and a crack formation of beams at change of flight of a cut and schemes of reinforcing are defined.
