This study aims to investigate the fexural behavior of reinforced concrete (RC) beams strengthened using aluminum honeycomb sandwich panels (AHSPs) with three diferent thicknesses (6, 10, and 15 mm) and CFRP U-Jackets with diferent
cross-section confgurations (i.e. support and middle sections). The experimental performance of RC beams was evaluated
utilizing AHSPs and CFRP composites under four-point bending tests. The strengthened RC beams (HCRC-2-HCRC-10)
were compared with the control beam (HCRC-1) in terms of fexural load carrying capacity, ductility, failure modes, and
cracks patterns. The results revealed that the HCRC-9 beam specimen strengthened using 15 mm thickness AHSP displayed
higher fexural performance than its counterparts. The HCRC-9 beam exhibited more ductile behavior, which depends on
the failure mode. Strengthening with AHSP decreased visible width shear cracks compared to the un-strengthened beam. It
was also detected that increase in the thickness of AHSP improved the fexural behavior of RC beams.
