PROBLEM TO BE SOLVED: To provide a new reinforcing method which contributes to reduction of a workload carried out by qualified workers, and quick personnel distribution, and is advantageous for shortening of a construction period and reduction of construction costs. SOLUTION: An existing steel structural member 12A is formed of an H steel having flange plates 14 opposed to each other, and a web plate 16 connecting between the flange plates 14. Then a flange 2202 of each angle steel 22 is set to the flange plate 14 at a location close to a lateral edge, and the former and the latter are temporarily fastened together by driving a driver 26 or a rivet (first temporary fastening step). Further a steel plate 20 is set and positioned to a flange 2204 of each angle steel 22, and the former and the latter are temporarily fastened together by driving the driver 26 or the rivet (second temporary fastening step). Furthermore the entire area of an edge located at each lateral end of each steel plate 20 is connected to an end of the flange plate 14 on the flange 2204 by welding Y1. COPYRIGHT: (C)2008,JPO&INPIT
