BEHAVIOUR OF FRP REINFORCED CONCRETE PANELS UNDER EFFECT OF FIRE

Popis výsledku v původním jazyce

New type of composite FRP (Fiber Reinforced Polymers) reinforcement has been developed in recent years at Brno University of Technology, which is fit for standard reinforcing, strengthening and pre-stressing of concrete structures. Advantage of FRP reinforcement are namely resistibility against aggressive environment and possibility to use smaller cover of reinforcement. However high demands on durability and resistibility against outer influences are required in modern construction and therefore next part of the research is concentrated on resistibility of structures reinforced by FRP reinforcement under effects of fire. The paper deals with experiments specially aimed on behaviour of pre-stressed and non pre-stressed panels subjected to fire effects. The behaviour of test panels during the fire was compared using different thickness of test structures together with the influence of the pre-stressing. These tests were completed with the tensile strength test under fire conditions of the reinforcement bars alone. The results demonstrate that in case of good anchoring of FRP reinforcement it is possible to use this reinforcement for load transfer even after significant damage (even burn-out of epoxy matrix) done by fire.
