Problem statement: This study showed the results of an experimental investigation on the strengthening of corrosion damaged reinforced concrete beams with unidirectional cloth glass fiber reinforced polymer (UDCGFRP) laminates. Approach: All the beam specimens 150×250×3000 mm were cast and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as ...

Interlaminar shear strength (ILSS) of fiber reinforced polymer composite is an important property for most of the structural applications. Matrix modification is an effective method used to improve the interlaminar shear strength of composite. In this paper, EPON 862/w epoxy system was modified using Tetraethyl orthosilicate (TEOS) electrospun nanofibers (ENFs) which were produced using electro...

The use of fiber reinforced polymer (FRP) bars in reinforced concrete members enhances corrosion resistance when compared to traditional steel reinforcing bars. Although there is ample research available on the behavior of FRP bars and concrete members reinforced with FRP bars under elevated temperatures (due to fire), there is little published information available on their post-fire residual ...

The present paper is concerned with modelling damage and fracture in notched woven fabric composites. Previous experimental work has shown that damage at a notch in a variety of GFRP and CFRP composites based on woven fabric reinforcement comprises matrix damage and fibre tow fracture along the plane of maximum stress. It is these experimental observations that inform the failure modelling deve...

The combined use of recycled concrete aggregate (RCA) and glass fiber reinforced polymer (GFRP) reinforcement in (RC) structures is deemed plausible to achieve sustainable construction. This paper aims examine the effect such a combination (RCA + GFRP reinforcement) on shear behavior RC beams. Six medium-scale beams (150 × 260 2200 mm) critical were tested under three-point loading until failur...

Offshore structures are exposed to risks of vessel collisions and impacts from dropped objects. Tubular members extensively used in offshore construction, thus, there is scope investigate their crashworthiness behaviour. Aluminium, glass fibre reinforced polymer (GFRP) hybrid aluminium/GFRP circular tube specimens were fabricated then tested under quasi-static dynamic axial loading conditions. ...

Several past studies have shown the use of glass fibre-reinforced polymer (GFRP) bars to alleviate reinforced steel rusting issue in different concrete structures. However, practise GFRP columns has not yet achieved a sufficient confidence level due lack theoretical model found literature. The objective current study is introduce novel prediction for axial capability made with GFRP. For this pu...

In this study, a multi-spot laser scanning thermography (MLST) system is developed for automated, rapid and long-range inspection of delamination in composite structures. First, thermal waves are generated by scanning a multi-spot laser beam over a target composite structure, and the corresponding thermal waves are measured by using an infrared (IR) camera. Then a thermal image processing algor...
