PROBLEM TO BE SOLVED: To provide a seismic strengthening method which can impart high earthquake-resisting performance to an existing building of a rigid-framed structure of reinforced concrete construction or steel-reinforced concrete construction at low construction cost and a small amount of construction work. SOLUTION: A seismic strengthening building frame 24 is constructed in close vicinity to the existing building 10 of the rigid-framed structure of the reinforced concrete construction or the steel-reinforced concrete construction. An existing external beam 14 of the existing building 10 and a reinforcing steel beam 22 of the seismic strengthening building frame 24 are joined to each other without connection between an existing external column 12 of the existing building 10 and a reinforcing column 20 of the seismic strengthening building frame 24. Thus, the existing building 10 is seismically strengthened by making the seismic strengthening building frame 24 bear a horizontal force during earthquakes. COPYRIGHT: (C)2010,JPO&INPIT |
