Hybrid Reinforcement

An experimental investigation was conducted to evaluate the performance of various types of glass fibre reinforced polymer (GFRP) reinforcement, including bent stirrups and headed bars in concrete structures. Results from 11 large beams (400 mm × 650 mm × 3650 mm) tested in monotonic three-point flexure were selected for this paper; some specimens used GFRP bent-bar stirrups and some used double-headed straight bar shear reinforcement. Based on the results from the tests, specimens reinforced with bent-bar stirrups and specimens with headed-bar shear reinforcement were found to perform similarly up until the calculated flexural failure load. Beyond that, beams reinforced with bent-bar stirrups showed significantly more deformability due to confinement of concrete in flexural compression. Strains measured in the transverse reinforcement were found to exceed the code limitations, in some cases exceeding 200% of the limit prescribed in both CSA S6 and ACI440.1R. It was also found that at loads close to the service conditions, the cracking behaviour was very similar for the beams reinforced with transverse headed bars and bent-bar stirrups. Finally, the concept of hybrid reinforcement systems for controlling deflections and cracking was introduced. Results from the experiments show promise that these systems can better control deflections and cracking at expected service load conditions.

The Impact

The purpose of this work is to study the best number of layer with the higher impact energy using Glass Fibre Reinforced Polymer (GFRP). The number of layers used in this study was 25, 33, 41, and 49. The impact test was performed using Single Stage Gas Gun (SSGG) for each layers given above with different bullets such as blunt, hemispherical and conical bullets. The gas gun pressure was set to 5, 10, 15 and 20 bar. All of the signals captured from the impact test were recorded using a ballistic data acquisition system. The correlation between the impact energy in terms of number of layer and type of bullet from this test are presented and discussed. It can be summarise that as the number of layer increases, impact energy also increases. In addition, from the results, it was observed that by using different types of bullets (blunt, hemispherical, conical), there is only a slight difference in values of energy absorbed by the specimen.

Chopped Strand Mat

Fibre reinforced polymer (FRP) plates subject to quasi-static indentation loading were studied. The plates were fabricated from three layers of chopped strand mat glass fibre and polyester resin using vacuum infusion process. Indentation tests were conducted on the plates with loading rates of 1 mm/min, 10 mm/min, 100 mm/min and 500 mm/min using a hemispherical tip indenter with diameter 12.5 mm. The plates were clamped in a square fixture with an unsupported space of 100 mm × 100 mm. The loads and deflections at the indented location were measured to give energy absorption-deflection curves. The results showed that the loading rate has a large effect on the indentation behaviour and energy absorbed.
