Based on the tests of twenty beams, the failure type, the ultimate strength and the influence factors of
reinforced concrete beams strengthened with externally bonded carbon fiber reinforced sheet are researched and analysed. The formula for estimating the shear capacity is put forward, which can give reference to application.
