ABSTRACT Fiber Reinforced Polymer (FRP) composite systems can be used for shear strengthening of reinforced concrete (RC) members. The present study investigated the shear performance and the modes of failure of simply supported RC T-beams externally strengthened in shear with FRP composites. Two different FRP-based strengthening systems were investigated, namely, externally bonded FRP sheets a...

Abstract In this study, the efficacy of strengthening reinforced concrete (RC) beams in shear by utilizing high-performance fiber-reinforced (HPFRC) was explored. The achieved epoxy bonding prefabricated HPFRC strips or plates onto beams. were strengthened two different schemes: (i) side (ii) vertical applied at critical sections. behavior configurations compared to non-shear and shear-reinforc...

We propose a new approach of direct detection SDMWDMFSO beams using the newly developed resonant cavity (RC) 4×4 photodetector (PD) array device, which integrates functions in such as an waveguide grating (AWG), multi-parallel photoreceivers, and mitigating optical alignment tolerance conventional WDMFSO system into one chip. The RC-PD device worked for not only wavelength separation WDM beams,...
