PROBLEM TO BE SOLVED: To provide a seismic strengthening structure that can efficiently enhance a load-carrying capacity of an existing building and that enables relatively free planning of a vertical traffic line after seismic retrofit.;SOLUTION: In a seismic strengthening structure, a reinforced structure R is retrofitted to an existing building T. The reinforced structure R is equipped with a reinforced staircase 3 that is elongated along a plane of structure to be reinforced in the existing building T. The reinforced staircase 3 functions as a brace and makes a shear force during an earthquake transferred to a downstairs side from an upstairs side.;COPYRIGHT: (C)2012,JPO&INPIT
