Table 5: Comparison of ultimate load and ultimate load deflection of the control beam with other specimens. For specimen GF-3 TR with a trapezoidal tendon profile layout and eccentricity at the end (e\({}_{\rm e}\)) = 0, the load-deflection curve is observed in Figure 10c. Its elastic stage is greater than the control beam; the first crack appeared in the concrete at 154.12 kN with a deflection of 1.42 mm. It has a higher ultimate load of 386.72 kN and a smaller deflection of 32.36 mm at the ultimate load.
