Title of the articleComparative evaluation of the carrying capacity, crack resistance and deformability jumper with standard and fiber reinforcement
Abstract.This article provides an analysis of the existing technology of the most popular products of modern construction is reinforced concrete beams residential and civil buildings. It is shown that the standard construction of reinforced concrete bridges including virtually the entire range of reinforcement products – working the longitudinal and transverse reinforcement and constructive mounting hardware does not meet modern requirements in terms of complexity and cost of manufacturing and does not allow to use the advanced technology of formless molding for manufacturing these products. The use of particulate reinforcement for the type of products and designs, and eliminates cross-mounting hardware, reducing the overall effort required to make them. Theoretical calculations of the bearing capacity and crack standard beams 3PB16-37 with the traditional and steel fiber concrete confirmed the possibility of reinforcing the perception of lateral forces dispersed reinforcement. The presented experiments on the relative beams capacity and deformability crack steel fiber concrete standard and beams have confirmed the correctness of theoretical calculations. Our studies allow us to recommend steel fiber concrete beams to implementation in production.
Keywords.Steel fiber concrete, a beam, the disperse reinforcing, bearing ability of section, the lateral force, bending moment, crack resistance, deformability.
