SEISMIC STRENGTHENING STRUCTURE AND SEISMIC STRENGTHENING CONSTRUCTION METHOD FOR EXISTING BUILDING

摘要

A seismic strengthening structure and a seismic strengthening construction method for an existing building capable of strengthening only from the outside of the building without using reinforcements and interposing reinforcing bodies (bracing materials) and providing excellent earthquake resistance. In the structure, anchor bolts (18) are driven in a column body (12) or a beam body (14) positioned on the outer wall surface of the existing building, a reinforcement section steel (20) is fixed to the anchor bolts (18) to dispose it on the column body (12) or the beam body (14), and a fiber-reinforced concrete (28) is placed so as to surround the anchor bolts (18) and the reinforcement section steel (20) so that steel-concrete synthetic structural member (10) formed of the reinforcement section steel (20) and the fiber-reinforced concrete (28) is installed to be integral with the outer wall surface of the existing building. Also, when a building highly resistant to earthquake is requested, a brace type or a stud type vibration damping member may be installed at a reinforced portion.
