Natural Jute Fibre-Reinforced Polymer Composite System for Posttensioned Beam Strengthening in Flexure
Table 3
Deformability indices for beams designed to fail under flexure.
| Designation | First crack load (kN) | Avg. mid span deflection at first crack (mm) | Avg. mid span deflection at failure (mm) | Deformability index |
| Scheme A | CB1, CB2, and CB3 | 3.687 | 6.522 | 1.77 | Scheme B | JFB4, JFB5, and JFB6 | The first crack deflection was not observed in fully U-wrapped beams | ā | Scheme C | JFB7, JFB8, and JFB9 | 4.531 | 10.727 | 2.36 |
