FRP Retrofit Simulator

Adjust concrete compressive strength, internal steel bars, and external Carbon FRP wrap thickness to analyze strengthened beam flexural capacity.

Concrete Strength ($f'_c$)28 MPa
Steel Reinforcement ($A_s$)600 mm²
CFRP Thickness ($t_f$)0.50 mm
No FRP (0.0)Thick Wrap (1.5)
FRP Advantage: High strength-to-weight ratio. Non-corrosive external laminate wrapping increases live-load limits without adding dead-load.
Retrofit Configuration
Reinforced concrete beam retrofitted with purple CFRP external wrap sheet
