خلاصه مقاله:
Various experimental studies have been carried out on glass fiber reinforced concrete (GFRC), but in limited studies, the behavior of this type of concrete is evaluated using finite element method (FEM). In this study an analysis model is presented for predicting energy absorption capacity of glass fiber reinforced self-compacting concrete (GFRCSCC) beams and the results are compared with experimental study. For this purpose, the investigations are conducted in two experimental and numerical sections. In experimental section, the characteristics of fresh and hardened concrete have been evaluated using slump flow, V-funnel, L-box, T50, compressive strength, tensile strength and flexural strength tests. In numerical section, ABAQUS software has been used to simulate GFRCSCC beams. The concrete damage plasticity model has been used to simulated concrete material. The fiber contents are 0, 0.25, 0.75 and 1% of the mixed concrete by volume. The results show that the maximum increase in energy absorption capacity of beams compared to the plain concrete for 25, 35 and 45 concrete grade was 29, 33.2 and 53.75%, respectively. At last, the ultimate loads corresponding to the FEM are found to hold good agreement with experimental ultimate loads which validates the FEM.
