SEISMIC REINFORCEMENT STRUCTURE OF EXISTING OR NEW STEEL FRAME STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a seismic reinforcement structure of an existing or new steel frame structure composed of H-shaped steel column and H-shaped steel beam.;SOLUTION: The structure comprises a continuous fiber sheet disposed on the surface of a flange of an H-shaped steel column 1 and an H-shaped steel beam 2, a reinforcement plate disposed on the continuous fiber sheet, an inner reinforcement plate with studs in which both ends abut the flange end between the flanges of the H-shaped steel column and the H-shaped steel beam and a head is formed at the tip end, a continuous fiber sheet disposed on the inner reinforcement plate, an outer reinforcement plate disposed on the continuous fiber sheet, a connecting reinforcement member 8 located at the intersection of the H-shaped steel column and H-shaped steel beam, having a portion abutting the web of the H-shaped steel beam, a portion abutting the flange surface of the H-shaped steel column, and a portion bent at a right angle from the flange end of the H-shaped steel column toward the web of the H-shaped steel beam, a connecting bolt 10 for connecting the connecting reinforcement member abutting on both sides of the web of the H-shaped steel beam, and a solidification material filled in the space between the H-shaped steel column and H-shaped steel beam and the inner reinforcement plate.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2019,JPO&INPIT
