Experimental and Numerical Analysis of GFRP Reinforced Beam

Original language description

This paper provides an overview of performance, durability and applicability of Glass Fibre Reinforced Polymers (GFRP). Concrete beams reinforced with GFRP bars were casted and after 28 days tested during the experimental part of the work. For comparisonpurposes same beams reinforced with steel bars were also prepared. A non-linear computer program ATENA 3D was used to simulate the experimental measurements. It was shown that the numerical results are very close to the actual experimental results and therefore it was recommended to use this program to model similar tests in the future. Both experimental and numerical results showed that GFRP reinforced beams have higher ultimate limit state (ULS) strength at flexure in comparison with steel reinforcement. However, deflections of GFRP reinforced specimens were unacceptably high. It was therefore concluded that serviceability limit state (SLS) will govern the design of concrete elements reinforced with GFRP.

Experimentální a numerická analýza trámku s GFRP výztuží

Czech description

Tento příspěvek je zaměřen na chování betonového trámečku se skleněnou výztuží. Trámeček je zkoušen ve stáří 28 dní. Pro srovnání je vyroben stejný trámeček s konvenční ocelovou výztuží. Oba vzorky jsou podrobeny čtyřbodovému ohybu. Je zaznamenáván průhyb pod oběma břemeny a uprostřed nosníku. Současně je uskutečněn numerický model. Trámeček s GFRP vykazuje veliký průhyb. Proto MSP je limitující faktor pro návrh.
