Finite Element Modeling of High Strength Self-Compacting Concrete T-Beams under Flexural Load Reinforced by ARFP

Abstract

A finite element models were constructed for comparison self-compacted concrete (SCC) T-beams to study a behavior change of these that reinforced with aramid fiber reinforced polymer (AFRP) and steel bars when compared with experimental data. Nine T-beam specimens reinforced with ARFP and three beams reinforced with steel bars were modeled and analyzed. The key variables were different high strength self-compacted concrete compressive strength, different ratios of AFRP and conventional steel bars for comparison. The comparison for output of flexural strain, load-deflection relationship and crack propagation are taken into consideration. The FE models by using (ANSYS) software show good agreement with the experimental data from previous study by (Yaseen, 2020). The numbers of cracks were reduced in all FE models while the final crack spacing was smaller than experimental samples by maintain the final deflection. Beams reinforced steel bars show better load capacity than those reinforced by AFRP. The FE models were stiffer than the experimental beams. The overall trend of analytical and experimental beam capacity vs reinforcement ratio, shows that the ANSYS response was conservative compared with experimental data of SCC AFRP reinforced beams.
