PROBLEM TO BE SOLVED: To provide a structure of the junction of RC frames and braces as well as an RC frame attached with a brace, which ensure the sufficient secureness and the easy fitting of gusset plates of braces.SOLUTION: An RC frame 4 consisting of a column 1 and a beam 2 is attached with a brace 3 connected to a brace gusset plate 5 fitted at a beam-column junction of the RC frame 4. The brace gusset plate 5 consists of a gusset plate body 6 projected at the internal angle part of the beam-column junction, a plurality of implantation plates 7 embedded in the end parts of both the column 1 and the beam 2 near the beam-column junction, and a plurality of protrusion 8. The plurality of implantation plates 7 are embedded in parallel to the structure plane of the RC frame 4. The plurality of protrusions 8, being projected from the plurality of implantation plates 7, are buried pointing outwards from the structure plane of the RC frame 4. Orthogonal plates 9 are fitted to the inner faces of the column 1 and the beam 2 roughly perpendicularly to the structure plane of the RC frame 4. |
