Abstract

This paper proposes a method of reinforcing an H-section steel beam web with an opening for MEP piping at one end, that is fixing ready-made flat bars or/and angles by fillet welding on the web areas above and below the opening, in parallel to the beam's axial direction, so as to provide the bearing force equal to that of a beam without any opening and sufficient deformation capability, for the purposes of simplification and cost reduction of the reinforcement. We demonstrated its reinforcement effects by FEM analysis and a quasi-static loading test, and developed bearing-force evaluation equations for the areas around such openings to establish the design method.
