Design the frp for a simply supported beam with length l 7

Question

Design the FRP for a simply supported beam with length L = 7 m.

The external uniform dead and live loads are: w_DL = 11.25 N/mm (Dead), and w_LL = 13.25 N/mm (Live).

The geometric and material data of the RC structure and FRP are: concrete, f^'_c = 34.5 MPa, width b = 300 mm, height h = 500 mm, d = 460 mm; longitudinal steel reinforcement, A_s = 1, 000 mm², f_y = 413 MPa; FRP, f^'_fu = 2, 800 MPa, ε^'_fu = 0.016, t_f = 0.33 mm.
