Abstract: |
Crack Formation of Flexural Members made of UHPFRCFor the design and planning of buildings made of fibre reinforced ultra high performance concrete one needs very detailed knowhow about the tensile carrying behaviour of fibrated concrete. It is affected by various parameters such as the fibre geometry, the content of fibres, the bond strength between fibre and binder matrix, the strength of the matrix, the shrinkage of the concrete and the orientation of the fibres. All these parameters are considered in a theoretical model for UHPFRC under tension (Leutbecher). In the paper presented here the range of validity of this model is extended to bending stress. Experimental investigations on UHPC-plates under bending complete and verify the theoretical results. The tests cover fibre reinforcement as well as conventional passive reinforcement. |
