Aseismic reinforcing structure
The present invention provides an aseismic reinforcing structure capable of improving the aseismic performance of an existing column without causing a crack in the existing column by a reinforcing column for the existing column and existing beams. A reinforcing column (8) is erected at a position outside an existing column (2) located on the building outer wall side of an existing building so as to face the existing column with a space (7) therebetween. The lower portion of the reinforcing column (8) is linked to a reinforcing beam (9L) fastened to an existing beam (1L) integrated with a floor slab (5L). The upper portion of the reinforcing column (8) is linked to a reinforcing beam (9U) fastened to an existing beam (1U) integrated with an upper-floor floor slab (5U). The reinforcing beams (9) fastened to the same existing beam are discontinuous with right and left adjacent reinforcing beams thereof. Even if a difference occurs between the deformation of the reinforcing column and the deformation of the existing column when external force acts, the existing column is little affected by the deformation of the reinforcing column, and hence the occurrence of a crack in the existing column can be reduced to a minimum.
