The size effect is a well-known characteristic of concrete structures. However, in the case of fibre-reinforced concrete (FRC), this issue is not thoroughly explored. Most design recommendations of FRC neglect the size effect or handle the behaviour of FRC structures in case of different structural sizes similar to plain concrete structures (assumi...

Fiber-reinforced concrete (FRC) structures are mainly designed using finite-element software. The input parameters used in these methods are based on the material properties of FRC obtained from test results. Because the experimental results of FRC show huge deviations, the material properties determined by an ordinary number of experiments do not...

This article shows through the analysis of three independent tests that the presented new semidiscrete analytical (SDA) beam model is efficiently applicable in the evaluation of test results. The model is based on fracture mechanics, takes the real distribution of the macrofibers into consideration in the critical cross-section of the beam, and use...

The use of fibre reinforced concrete has significantly increased in recent years. Despite a considerable amount of research, fibre reinforced concrete (FRC) has not been standardized yet. The aim of the present survey is to work out a new semi-discrete beam model which takes the real distribution of the fibres in the critical cross-section of the F...

The pull-out behaviour is one of the distinctive features of fibre reinforced concrete. Few analytical models for the pull-out of synthetic fibres can be found in the literature. Moreover, the existing models are not supported by comprehensive experimental investigations. In this research experimental investigations have been carried out. First, th...

In recent years, fiber reinforced concrete has been increasingly used not only for industrial floors but for many other loadbearing structures as well. The different types of synthetic fibers have distinct effects on concrete: micro fibers to reduce plastic shrinkage cracking of concrete, and macro fibers to give higher fracture toughness. This pap...
