In this method, sprayed glass fiber reinforced concrete (GFRC) with basalt textile reinforcement is used for external confinement of columns. Four reference and eight retrofitted specimens with square (200x200 mm) or rectangular (200x300 mm) cross sections were tested under monotonic axial loading. Test results showed that the proposed retrofitting technique is quite promising for retrofitting of low strength concrete members in terms of strength, and particularly deformability. The enhancement of strength and deformability is also predicted analitically based on the concept of effectively confined section geometry and it is shown that the experimental results and analytical predictions are in a good agreement. Consequently, this type of retrofitting can be considered for stregth and deformability enhancement of substandard reinforced concrete columns in seismic prone areas.
