<P>PROBLEM TO BE SOLVED: To provide an earthquake strengthening structure by post-mounting steel frame brace to be used only as a compression member for a reinforced-concrete building, and an earthquake strengthening method. <P>SOLUTION: In one diagonal direction of an opening part 3 formed from a post 1 and a beam 2 of a reinforced-concrete building, a main brace 4 including a folding point 4a in an intermediate part is disposed in a bent state where eccentricity (e) of the folding point 4a occurs in another diagonal direction. Both end portions of the main brace 4 are fixed to corresponding corner parts 7 and 8 of the opening part 3 formed from the post 1 and the beam 2 in an abutting state. An auxiliary brace 5 is disposed between a constituent portion 4A of the folding point 4a of the main brace 4 and a corner part 8' of the post/beam opening part 3 opposed in the other diagonal direction where the eccentricity (e) of the folding point 4a occurs. <P>COPYRIGHT: (C)2013,JPO&INPIT |
