Characterization tests for predicting the mechanical performance of SFRC floors: identification of fibre distribution and orientation effects

Abstract In the context of evaluation load-bearing capacity a steel fibre reinforced concrete (SFRC) elevated slab recently built in northern Italy, this paper presents study addressing effects distribution and orientation. An extensive experimental programme was carried out collaboration between Politecnico di Milano Universitat Politècnica de Catalunya. The included mechanical tests on four shallow beams six notched standard beams. Additionally, uniaxial tensile (UTTs), double edge wedge splitting (DEWSTs) punching (DPTs) 192 drilled core samples extracted from were performed. Inductive tests, measuring self-induction change that occurs when SFRC sample is placed inside coil, performed all subjected to DPTs assess distribution. This compares direct indirect for definition FRC post-cracking constitutive law, highlighting advantages disadvantages each test type. A comparison non-standard also presented. Mechanical non-destructive different directions at locations have allowed orientation which provide an estimation possibility using these as simplified production control.
