摘要

PROBLEM TO BE SOLVED: To provide a reinforcement structure capable of reinforcing a beam-column joint irrespective of newly constructed and existing buildings.;SOLUTION: There is provided a reinforcement structure (12) of a joint of a square joint steel pipe (14) having four side faces (14a to 14d) and an upper diaphragm and a lower diaphragm (16 and 18) joined to the joint steel pipe, and a beam (24) formed of a steel frame having an H-shaped cross-sectional shape. The reinforcement structure includes one steel plate members (26 and 28) arranged in parallel to both of the upper and lower diaphragms in the periphery of the joint steel pipe related to one beam using one side face of the joint steel pipe as a joint surface. The one plate member is welded to a first side face of the joint steel pipe forming the joint surface and a second side face adjacent to the first side face, and one of both of mutually facing surfaces of a web (24c) of the one beam.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
