Numerical study on shear strengthening of reinforced concrete (RC) deep beams with and without stirrups using near-surface mounted FRP bars
… or repair RC members. Fibre reinforced polymers (FRP) bars are commonly used through the NSM technique to strengthen RC members. However, limited studies on NSM strengthening using FRP bars on RC deep beams are available. In this research, a numerical investigation was carried out on RC deep beams …

Investigating the use of fiber-reinforced polymer bars in concrete
Fiber Reinforced Polymer bars were introduced to the market over two decades ago. However, their use is still somewhat limited. FRP bars are very corrosion resistant and with much of the US infrastructure degrading, the use of FRP bars over conventional steel has been proposed as a fix to this …
