PROBLEM TO BE SOLVED: To provide a method of reinforcing the joint (of a beam-penetrating type) of a column made of reinforced concrete or steel-frame reinforced concrete and beams made of steel-frame, steel-frame reinforced concrete or steel-frame concrete, using reinforcing bars for shearing, and provide the reinforced joint structure of a column and beams. SOLUTION: Steel-frame beams have top and bottom flanges in vertical section. Welded metal meshes or reinforcement grids are used as reinforcing bars for shearing. From a plan view of this joint of column and beams, welded metal meshes surround the external circumference of column's main reinforcements, its vertical length is housed within the top and bottom flanges of each beam and its lateral ends draws near each two adjacent steel-frame beams. At least one vertical reinforcing bar at both ends of the welded meshes is located within an area of the top and bottom flanges of adjacent beams to be filled with concrete placed. The welded metal meshes etc. is installed by connecting them with main vertical reinforcements etc. using wires. COPYRIGHT: (C)2005,JPO&NCIPI
