Abstract:
This paper introduces a rectangular concrete-filled fiber reinforced polymer (FRP) tube (CFFT) hybrid beam with an inner voided tube. The beam contains an outer rectangular filament-wound glass fiber reinforced polymer (GFRP) tube, and an inner voided circular filament-wound GFRP tube shifted toward the tension zone. The space between the tubes is filled with concrete. Steel bars, at the tension side, were provided to enhance both stiffness and serviceability of the beam. The flexural behavior of this voided CFFT beam was compared with a fully CFFT beam and another conventional steel reinforced concrete (RC) beam having identical dimensions. The results
showed that the new hybrid composite beam behaves positively in terms of strength, ductility, and failure
propagation, in addition to its high durability. The results also showed that, while the weight of the voided CFFT
beam is 30% lighter than the weight of the conventional RC beam or the fully CFFT beam, its flexural capacity is
141% and 6% higher than their flexural capacities, respectively.
