STEEL GIRDER REINFORCED USING FIBER REINFORCED POLYMER

摘要

The present invention relates to a steel girder comprising a fiber reinforced plastic stiffening member with an antislip structure for an end unit, wherein the fiber reinforced plastic stiffening member is coupled to the lower surface of the steel girder in the case of changes in building conditions and the breakage of members caused by collision and corrosion in the existing steel girder. In accordance with an embodiment of the present invention, the steel girder comprises a steel girder; a stiffening member which is made of fiber reinforced plastics and has an attachment surface of which the outer end unit is diagonally cut in order for the upper cross section to be narrower than the lower cross section and a connection support hole formed by passing through both ends thereof; and an adhesive bonding the lower surface of the steel girder to the stiffening member by filling in between adhesive surfaces of the steel girder and the stiffening member and in both an adhesive layer of the steel girder, the stiffening member and the connection support hole.
