Investigation of Fracture Properties by Inverse Analysis on Selected SCC Concrete Beams with Different Amount of Fibres

Popis výsledku v původním jazyce

Self-compacting concrete (SCC) and Steel fibre reinforced concrete (SFRC) have higher tensile strength capacity, limited crack width and higher post peak capacity, as well as easier construction handling. Thus SFRC allows for advanced and innovative design of concrete structures. However, the current wider structural applicability of the discussed composite material is limited by lack of knowledge and recommendations for advanced design and analysis considering non-linear calculation as well corrosion related durability. Therefore, it is necessary to have knowledge of several physical and mechanical properties or to be able to identify the properties of interest. The article presents the results of the identification of fracture properties of selected self-compacting concrete that are suitable for nonlinear finite element analyses. Moreover, the ability of selected concrete to the ingress of chlorides is of particular interest as well. Interest in material properties consisted of concrete tensile strength, modulus of elasticity, softening factors and specific fracture energy. The procedure for identifying material properties by inverse analysis was applied. New knowledge of material properties can be used to analyse similar tasks, especially in the case of nonlinear analysis of concrete structures. (C) 2018 The Authors. Published by Elsevier B.V.
