Circular design are becoming increasingly used in construction. This paper presents an experimental study of fibro - reinforced concrete and concrete elements of circular cross-section under the joint action of the longitudinal axis, compressive and shear forces. Experimentally confirmed the effectiveness of fiber reinforcement as a warning of avalanche damage, increased fracture toughness designs. Experimental data on the stress-strain state and strength of fibro - concrete elements of circular cross-section in lateral bending and the joint action of the longitudinal and transverse forces, using the original installation, to provide the new scientific results are in satisfactory agreement with theoretical considerations. Also noted the addition of longitudinal compressive force increases the carrying capacity of concrete and fiber - reinforced concrete elements of an oblique section under the action of shear forces.
