Shear tests on SFR-UHPC beams with or without web opening

Abstract

This paper presents the experimentally obtained shear behaviour of SFR)UHPC (steel fibre-reinforced ultra-high performance concrete) I-shaped beams with or without web openings. Steel fibres added to the concrete replace the stirrups. A comparison between beams with diagonal rebar and without is made. The shear carrying capacity of UHPC beams is significantly increased compared to normal strength or even high strength concret
