Finite Element Analysis of RC Beams with Rectangular Web Openings in Flexure Zone Strengthened with CFRP

This paper presents a nonlinear Finite Element Analysis (FEA) that has been carried out to study the behavior of fiber reinforced polymer (FRP) strengthened reinforced concrete (RC) beams containing large rectangular web openings in the flexure zone. Studied parameters were type of loading and opening size. Eleven RC beams categorized into two different groups were adoptable in FE model software using ANSYS V14. The analysis results compared with five experimental beams had been done by Almusallam et al. 2018 . In the first group, eight beams were tested under
center-point loading. They comprised of one reference solid beam and seven beams with large rectangular web opening with different dimensions located at the maximum-moment region. Out of the seven beams with openings, four beams were unstrengthened and the other three were strengthened with carbon fiber reinforced polymer (CFRP) sheets. In the second group, three beams were tested under four-point bending. They comprised of one reference solid beam (without opening) and two beams with large rectangular web opening in the pure flexure zone. Out of the two beams with openings, one specimen was unstrengthened and the other one was strengthened with (CFRP) sheets. The failure loads, crack pattern and mode of failure were analyzed here in this study.
Keywords- Finite element analysis (FEA), openings, flexural strengthening, FRP.
