摘要：

An experimental program was developed in which dry carbon and glass fiber wires bundles were spirally wrapped around five longitudinal steel bars with 8 mm diameter to act as a passive confinement inside the concrete stub columns. Stub columns were manufactured using 150 x 300 mm cylinders with a different number of fiber wires as transverse reinforcement. It was observed that bundling 20 strands of CFRP fiber yarns and bundling 30 strands of GFRP fiber yarns gave ductile response. However, the use of 20 bundled wires of CFRP out-performed the 30 bundled wires of GFRP in terms of ductility but not strength.
