Crack width in reinforced steel fibre concrete

TL;DRAbstract

Nowadays durability plays a bigger and bigger role in structures. The so-called crack width is a very important issue in the durability. The addition of steel fibres to the concrete matrix is not unheard of and tests concluded that the crack width can be reduced. Currently steel fibres are added to the concrete matrix in different projects, however these projects were mainly floors. For more general use of steel fibres, calculation rules are needed. The main question of this graduation thesis was to study the influence of steel fibres on the crack width. The study of the crack width in steel fibre concrete shows that the steel fibres influence the transmission length and the steel stress. A crack width expression has been derived in two different ways: a semi-empirical method and by the use of differential equations. The expression which is found is the same expression as found in reinforced concrete without steel fibres. In this expression an extra variable has been added, the variabl
