Abstract:
This paper aims to investigate 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,
opening size and strengthening scheme. Seven RC beams categorized into two different groups were tested. In the
first group, two unstrengthened beams (one solid without opening and one with large rectangular web opening
in the pure flexure zone) were tested under four-point bending. In the second group, five beams were tested under
center-point loading. They comprised of one reference solid beam and four beams with large rectangular web opening
in the maximum-moment region. Out of the four beams with openings, two specimens were unstrengthened
and the other two were strengthened with two different FRP schemes. A numerical study was also conducted and
the results of analysis were validated with experiments. The calibrated analysis was then used for some useful parametric
studies in which the effect of different parameters was investigated.
