【Abstract】 Eight simply supported beams strengthened by carbon fiber sheet are tested. The main work is how to calculate the effect of the FRP for concrete beams. The experimental factors are strengthening mode, width and space of CFS strips, layers of the strips, shear span/depth ratio and concrete strength. Finally, the formula for estimating the shear capacity is put forward, which can give reference to application.更多还原
