A radar NDE (nondestructive evaluation) technique using an airborne antenna operating in the far-field condition is developed for detecting damages such as delamination and concrete cracking in GFRP (glass fiber reinforced polymer)-wrapped concrete columns. The far-field airborne radar (FAR) NDE technique is advantageous for distant measurement of bridge columns in practical applications. Far-f...

Soil reinforcement can be considered as the combination of two parts. One part is soil for compressive stress capacity and another part is some material such as geosynthetics such as steel belts and fibers for tensile stress capacity. Soil improvement is one of the useful methods to increase the strength parameters of the soil. The main goal of this study is to evaluate the effects of GFRP on t...

Some of the advantages that results from the structural strengthening of concrete slabs using prestressed fiber reinforced polymer (FRP) systems are as follows: the prestressed FRP delays the formation and propagation of cracks, and both the serviceability and the flexural capacity are increased. In this research program, the flexural performance of a concrete slab strengthened with a three-sta...

Unreinforced masonry (URM) walls are prone to failure when subjected to out-of-plane loads caused by earthquakes or high wind pressures. In this context, fiber reinforced polymer (FRP) materials may be a solution to solve or lessen the effects of this overloading. This paper describes an experimental program dealing with the flexural behavior of nine concrete URM walls strengthened with glass F...

Fiber-reinforced polymeric composites are used widely due to their unique properties of light weight, stiffness and high strength weight ratio. During processing and servicing, the composite materials undergoes delamination, and petalling. Computational model was constructed for finite element modeling to reflect material purpose under impact load and relevant material properties were taken. In...

The purpose of this study was to understand the deflection behavior reinforced concrete beams using GFRP bar as flexural reinforcement and sheet shear reinforcement. tested with dimensions span length were 3000 mm, width 150 mm height 250 quality f'c.25 MPa. use 3D13 U-wrap 50 wide a distance 100 mm. is only installed in spans. beam loaded two concentrated loads monotonically until it collapses...
