摘要：

A full-scale failure test of a post-tensioned and fibre reinforced flat-slab has been carried out. The structural system consisted of 2 by 2 spans (2 x 8,5m and 2 x 6,5m), and the slab was reinforced with tendons and 0,38 volume % steel fibres (30kg/m(3)). The load was uniform waterpressure, and strains and deflections were measured. The test is related to ongoing standardization work, and the major result is that the experimental capacities are considerably on the safe side if characteristic strength values and elastic theory for calculation of moment distribution are used. This holds both for the German design rules for fibre reinforced concrete (DIN-EN), for fib Model Code and the Norwegian guideline-proposal.
