Abstract [en]

The purpose of this study was to investigate the properties of steel fibre reinforced concrete and its design models in relation to conventional reinforced concrete from a mechanical, economical and ergonomic perspective. Design examples were also presented for beams and slabs-on-ground for their shear and moment capacity. For this reason, both bending tests and design calculations were performed to help compare the different reinforcing methods. The bending tests were performed on seven beams where three were conventional and four were reinforced with steel fibre. Half of the steel fibre beams were reinforced with 1 % of the volume amount while the other half contained 1.5 %. The design examples were all according to the new Swedish standard for fibre concrete, SS 812310: 2014 and the European standard for concrete structures, Eurocode 2. Examples of shear capacity in relation to the bending tests were given. This thesis also included design examples of moment capacity for slab-on-ground to show its wide area of use. According to the performed bending tests, it showed that beams reinforced with 1% and 1.5% steel fibres could effectively handle shear forces. In comparison to the conventional reinforced beams, the steel fibre beams had an increased shear capacity with a minimum of 20%.  The bending tests and the design calculations showed that steel fibres can replace stirrups as shear reinforcement. Clear ergonomic and economic benefits of reinforcing with steel fibres were shown. Handling of conventional reinforcement was physically stressful as opposed to the shorter casting process that came with steel fibre reinforcement which contributed to a better working environment.
