STRUCTURE AND METHOD FOR ASEISMIC REINFORCEMENT OF EXISTING BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a structure and a method for aseismic reinforcement of an existing building that enhances aseismic performance without closing an opening.SOLUTION: An aseismic reinforcement structure for an existing building 11 includes a steel member 25 disposed along a plurality of beams 13 of the existing building 11, a reinforcing bar 26M disposed along a wing wall 14s of the existing building 11, the reinforcing bar being connected to the steel member 25, and a concrete body 27 containing the steel member 25 and the reinforcing bar 26 and disposed along the beam 13 and the wing wall 14s. A length of a first reinforcing part 22 is longer than a length of a second reinforcing part 23, the first reinforcing part comprising the steel member 25 and the concrete body 27 disposed along the beam 13, and the second reinforcing part comprising the reinforcing bar 26M and the concrete body 27 disposed along the wing wall 14s, in a thickness direction of a wall part.SELECTED DRAWING: Figure 2
