Strenghtening of RC beams with bamboo fiber reinforced composite-polyester plate
The biodegradability of the natural fibers provides safe and environmental-friendly features toward the ecosystem, with the low cost and good performance of these fibers, it meets the demand of the industries. Bamboo is a massive natural resources in Asia and high mechanical strength of bamboo fiber...

The biodegradability of the natural fibers provides safe and environmental-friendly features toward the ecosystem, with the low cost and good performance of these fibers, it meets the demand of the industries. Bamboo is a massive natural resources in Asia and high mechanical strength of bamboo fiber can be characterised as natural glass fiber. This study presents the findings of an experimental study to investigate the beam performance and the failure modes of reinforced concrete (RC) beams under un-strengthened and strengthening condition using bamboo fiber reinforced composite (BFRC) embedded in polyester resin matrix. Circular openings of diameter 120 mm created at the shear zone were considered for strengthening under shear condition. The experimental work including physical, thermal and mechanical properties of the BFRC-polyester plate were conducted such as Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), tensile test (ASTM D3039) and flexural test (ASTM D790-03). In terms of structural properties, a total of six beams were tested under four-point loading. The variables investigated in this research study included the fiber volume ratio of BFRC-polyester plate ( 0 wt %, 10 wt %, 20 wt %, 30 wt % and 40 wt % ) and strengthened beams (with and without circular opening).
