SEISMIC STRENGTHENING STRUCTURE FOR BEAM, AND SEISMIC STRENGTHENING METHOD FOR BEAM

摘要

PROBLEM TO BE SOLVED: To provide a seismic strengthening structure for a beam, which is used to strengthen the beam having a deficiency of flexural strength and shear strength, and a seismic strengthening method for the beam.;SOLUTION: A strengthening steel plate 10 is fixed to an outdoor-side lateral surface of a beam 4 of steel framed reinforced concrete construction in a horizontally arranged state in such a manner that a cut-off part with a main reinforcement of the beam 4 reduced or a steel frame joint part of the beam 4 is set as a strengthening position.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
