An experimental investigation on the use of fiber reinforced polymeric (FRP) coating for out of plane strengthening of masonry walls

The effects of fiber reinforced polymeric (FRP) composite coating on the out of plane strengthening of the masonry walls was investigated using a 3-point loading test. It was found that the coating of masonry walls with FRP enhanced the ultimate transverse strength of the wall approximately 40%. Furthermore, retrofitting of masonry wall with FRP coating led to the higher ductility and energy absorption and subsequently, minimized the secondary damage possibilities including fragment generation in the high strain rate loads such as earthquakes.
