REINFORCEMENT STRUCTURE FOR ONE-SIDE WIDENED STEEL BEAM

摘要

PROBLEM TO BE SOLVED: To provide a reinforcement structure capable of reducing a decrease in bearing force of a one-sided widening steel beam according to the present invention.;SOLUTION: A reinforcement structure 10 for a one-side widened steel beam comprises: a steel beam 20 which is formed of H-shaped steel having an upper flange part 22 and a lower flange part 24 positioned one over the other and a web part 26, and has ends 20E joined to a steel column 30 and the upper flange part 22 joined to a slab; a pair of widening parts 40 which are provided at the ends 20E and widen flange widths of the upper flange part 22 and lower flange part 24 projecting from the web part 26 toward one side; and a pair of end ribs 50 which couple at least one of the upper flange part 22 and slab to the lower flange part 24 so as to restrict the lower flange part 24 from being displaced.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
