Project

Experimental investigation and modelling of Textile Reinforced Concrete under biaxial loading conditions unaligned with fibre direction (FWOTM916)

The research towards fibre textiles as reinforcement for concrete started in the early 80’s. Cementitious composites such as Textile Reinforced Concrete (TRC), which are low-tech, low-cost, fire-resistant and can be pre-cast, are more adapted for construction industry. Moreover, the use of non-corroding fibres and a fine-grained mortar allows to manufacture thinner concrete elements using a minimum amount of material, and thus contributing to a more sustainable construction industry.
Thin shell structures are one of the most promising applications of TRC because they exploit both the slenderness of the material and the form freedom of the fibre reinforcement. To accurately design these structures, however, the state of the art on TRC behaviour is not sufficiently advanced. One of the main barriers is the very limited knowledge on the material’s behaviour under complex stress states.
This project will include an extended experimental and analytical-numerical fundamental research program that will give an insight in the material's biaxial and off-axis behaviour. Analytical constitutive model of the tensile behavior of TRC will be developed, calibrated and verified according to the biaxial test results. Using this knowledge, different design strategies will be investigated for the TRC structures to increase their loadbearing capacity and at the same time be optimal in terms of material use and cost.
