Calculation of Shear Capacity of Steel and Concrete Composite Beams Strengthened with FRP

Some calculated methods of shear capacity of RC beams strengthened with FRP (fiber reinforced polymer) are reviewed based on the experimental data on shear capacity of RC beams strengthened with FRP. Therefore, according to the destruction forms of steel and concrete composite beams strengthened with FRP, the formula for calculating the shear capacity of the beams are given. The formula is expressed clearly, simple and easy to use.
