<P>PROBLEM TO BE SOLVED: To provide a frame reinforcement structure having earthquake resistance without installing a reinforcement part such as a stiffener to a beam while reducing the cost and man-hour. <P>SOLUTION: A column 1 and a girder 2 are joined to form a column-beam joint B, in the vicinity of which an angle-brace 5 is installed over the column 1 and the girder 2. The girder 2 is formed of a section steel having a pair of flanges 2a and 2b and a web 2c connecting the pair of flanges 2a and 2b. The girder 2 is provided with a non-reinforced region 2p between the pair of flanges 2a and 2b, and a connection part to the angle-brace is formed in the non-reinforced region 2p of the one flange 2b. The angle-brace 5 is provided with a component 5a1 having a rectangular cross section which is installed over the column 1 and the girder 2. The component 5a1 having a rectangular cross section satisfies a predetermined expression of a relation to the girder 2, and is connected to a connection part 2k of the girder 2, allowing the center line in the thickness direction to be aligned with the center line of the girder 2 in the thickness direction of the web 2c. <P>COPYRIGHT: (C)2013,JPO&INPIT |
