Influence of Steel Fibres in Steel Fibre Reinforced Concrete on ULS and SLS

Popis výsledku v původním jazyce

The steel fibre reinforced concrete is expensive compared with the ordinary concrete. The costs for the production, the transport and the setting of steel fibre reinforced concrete should be directly proportional to its quality. The quality of material can be quantified in a broad spectrum of properties (the workability, the mechanical and physical properties, the durability, etc.). This article is focused on the influence of mechanical and physical properties (the tensile strength and the residual tensile strength) on ULS and SLS. The paper is limited only to the bending load bearing capacity from ULS point of view and limited only to vertical deformation from SLS point of view. The example is a part of paper – the calculation of two bending structures. Firstly, it is calculated as the structure of ordinary reinforced concrete and secondly it is calculated as the structure of reinforced steel fibre reinforced concrete. The geometric arrangement, the type and the quantity of reinforcement are identical for both calculated structures. The calculated structures are different only in the tensile strength and the residual tensile strength. All other input parameters (including modulus of elasticity) are identical for both calculated structures, in order the influence of tensile strength on ULS and SLS excels. The presented results should be the basic concept for the effectiveness assessment of steel fibre reinforced concrete application.
