Abstract: Partial prestressing, unbonded tendons and high-strength concrete have become commonly used techniques and materials in the prestressed concrete industry. The effect of their application on the non-linear behaviour of continuous post-tensioned beams was studied in an experimental way at the Magnel Laboratory for Concrete Research of Ghent University. It was found that especially the high concrete strength had a negative effect on the moment redistribution and rotation capacity of post-tensioned continuous concrete beams. In a further study it was checked whether or not this negative effect can be reduced by the application of current steel fibres and micro-fibres in high-strength concrete.
