Özet:

The use of concrete filled fiber reinforced polymer (FRP) profiles for beams and columns has been studied extensively in recent years. Glass Fiber Reinforced polymers (GFRP) profiles are one of these materials. GFRP box profiles serve as formwork, and provide shear and flexural reinforcement in novel hybrid GFRP–concrete structural system. GFRP box profiles also protect the concrete and increase the strength of hybrid materials. This study presents results of an experimental study using concrete filled pultruded GFRP profiles. A series of compression tests were carried out to study the compression behavior of the proposed hybrid GFRP-concrete materials. Hybrid compression samples were fabricated and tested in three different strength classes. The results showed that compressive strength of hybrid material significantly increased when compared to reference samples.
