Fig. 4 Sectional details of Beam and column

The stress-strain curve of CFRP is used to increase the capacity and ductility of the beam and column. Stress-strain curve of CFRP Fig 1-5 is used. The ultimate stress of tension of CFRP is 800MPa and compression 280MPa.The curve shown is below Figs 6-8. The reference of the stress-strain curve of CFRP Essam B. Moustafaa et al. (2021).
