This paper presents experimental and analytical studies on the effect of the compressive strength of the concrete infill on the flexural behaviour of composite beams. Hollow pultruded Glass Fibre Reinforced Polymer (GFRP) square beams (125 mm x125 mm x 6.5 mm) filled with concrete having 10, 37 and 43.5 MPa compressive strength were tested under static four-point bending. The results indicate that filled GFRP beams failed at a load 100 to 141% higher than hollow beams and showed 25% increase in stiffness. However, the increase in concrete compressive strength from 10 to 43.5 MPa increased the ultimate load by only 19% but exhibited almost the same flexural stiffness indicating that a low strength concrete is a practical solution to fill the GFRP profiles to be used as beam applications. Moreover, the concrete infill prevented the premature buckling and web crushing of the GFRP tube. The maximum strain measured at failure is similar to the compressive strain determined from the coupon test indicating the effective utilisation of the GFRP material. Finally, Fibre Model Analysis which considered the partial confined stress -strain curve for the concrete infill gave an accurate prediction of the flexural behaviour of the concrete filled GFRP sections.

“…Design oriented models are normally in simple closed form and they can be used directly in practical design (Xiao & Wu 2000, Lam & Teng 2003. Analysis oriented models predict the stress-strain behaviour using iterative process (Spoelstra & Monti 1999, Binici 2005, Jiang & Teng 2007. Many of these models are based on an active confinement base model.…”

Ductility of High Strength Concrete (HSC) columns can be increased by lateral confinement. The conventional confinement with steel reinforcement may not always be adequate to provide the ductility levels desired by the engineer. The lateral confinement by FRP can provide significantly higher confinement stresses than the conventional steel reinforcement, and convenient for repair applications. Confining pressure applied by FRP is a function of the lateral strain of concrete. Therefore information of axial stress, axial strain and lateral strain relationships of concrete is fundamental in the design of confinement. Many existing models are based on test results with low confining pressures which are not suitable for modelling FRP confined concrete. The authors present a model in this paper which is suitable for use in designing FRP confinement of concrete. Model results are compared with experimental results of FRP confined columns. The results demonstrate the model is suitable for this use.
