Abstract: Research into reinforcing reinforced concrete (RC) deep beams with apertures using externally bonded basalt fiber reinforced polymer (BFRP) composite sheets is detailed in this article.
Nine deep beams with holes were built and put through their paces with a three-point load. A total length of 1000 mm and a cross-section of 150 x 500 mm were the dimensions of the test specimen. At the beam's midpoint, two holes were symmetrically positioned; one hole was in each shear span. Opening shapes and BFRP sheet orientation were among the test factors.
The degree to which the normal load route was interrupted largely determined the structural response of RC deep beams with apertures. The shear strength of RC deep beams was enhanced more by horizontally bonded BFRP strengthening around the apertures than by vertical strengthening.
The horizontal BFRP sheets increased the material's strength by 8–54%. Whereas, between zero and eighteen percent, strength is increased by means of vertical BFRP. An analytical technique was presented and compared with test results for the prediction of shear strength in RC deep beams with apertures reinforced with BFRP sheets.
