Influence of different mechanisms on the constitutive behaviour of textile reinforced concrete

Hartig, Jens, Jesse, Frank, Häußler-Combe, Ulrich 03 June 2009 (has links)
Textile Reinforced Concrete shows a complex load-bearing behaviour, which depends on material properties of the composite constituents and load transfer mechanisms in between. These properties cannot be modified arbitrarily in experimental investigations, which complicates identification of the impact of certain mechanisms on composite’s behaviour. In this respect, theoretical investigations offer the possibility to study the influence of individual parameters. At first, experimental results of tensile-loaded specimens are given, which help to identify different mechanisms in advance. Afterwards, respective results of numerical calculations with a reduced two-dimensional model are presented to study these mechanisms, including the effects of a reduced stiffness in the cracked state, yarn waviness and tension softening of the cementitious matrix.
