RC BEAMS STRENGTHENED IN SHEAR WITH HONEYCOMB STEEL MESH, CONSTRUCTION METHOD THEREOF

摘要

A reinforced concrete beam shear-reinforced by a honeycomb steel mesh, and the construction method thereof are provided to prevent the spread of shear cracks of a beam and to restrain initial shear failure effectively by arranging honeycomb steel meshes in reinforced concrete appropriately. A reinforced concrete beam shear-reinforced by a honeycomb steel mesh is formed by arranging tensile reinforcements and compressive reinforcements, and arranging honeycomb steel meshes between the tensile reinforcement and the compressive reinforcement of the reinforced concrete beam to reinforce shear force, wherein the honeycomb steel meshes are arranged on the front side and the rear side from the horizontal direction of the reinforced concrete beam and the length(L) of the diagonal width of a cell of the honeycomb steel mesh is 100mm~150mm.
