Structural Performance and Crack Control of Fibre Concrete Beams with Conventional Reinforcement

Popis výsledku v původním jazyce

Experimental study includes investigation of performance of concrete beams reinforced with conventional steel bars and with synthetic fibres. Several sets of beams have been tested to determine the influence of polypropylene fibre reinforcement on the mechanical behaviour of conventionally reinforced concrete beams in bending. The present study indicates that polypropylene fibre reinforcement can reduce crack width and deflections and improve ductility of beams and that the combination of polypropylene fibres, longitudinal steel bars (without stirrups) may meet strength and ductility requirements.The basic material characteristics were obtained from laboratory tests on prisms in four or three point bending and by an inverse analysis procedure the load-deflection relation were transformed into constitutive relations used in simulation. The test was simulated by means of a non-linear program system using various constitutive relations, which enable fibre concrete modelling.
