Numerical and experimental analysis of behaviour of steel fibre reinforced selfcompacting concrete slabs under loading

Abstract

The paper deals with testing of self-compacting concrete slabs with scattered steel reinforcement, which are designed for the production of garden furniture or benches. A self-compacting concrete was designed for the experiment and its composition was further modified by the addition of steel fibres. Plain self-compacting concrete was used to produce test specimens with nominal dimensions of 40x40x160 mm, which were used to determine the basic properties of concrete, and test slabs for experimental analysis of their behaviour under load. The self-compacting concrete with steel fibres was only used to produce test slabs. The slabs were loaded in three different ways, of which one was to simulate real loading of the horizontal part of a concrete bench. The results of the loading tests are compared to the results of a nonlinear numerical analysis conducted using the finite element method.The paper deals with testing of self-compacting concrete slabs with scattered steel reinforcement, which are designed for the production of garden furniture or benches.
