Abstract This thesis is experimental and numerical studies to investigate the performance of fully pre-stress two-way post-tensioned slab strengthening using CFRP Strips to prove its efficient work in two-way pt slabs action. taking into account some different parameters as bond tendon, unbonded tendon and pre-compression ratio. The experimental program included five post tension two-way slabs. The design was carried out for most widespread code ACI318-14, ACI440.2R-17and extent to compare the design requirements and the design results with ECP203. The numerical analysis using the Finite Element Method was implemented through ANSYS program. A good correlation between FE and experimental results. Performance of the fully pre-stress post tensioned two-way slab pre-strength with CFRP strips have better performance in boded rather than unbonded. and the effect of pre-compression in CFRP strain is the same for different values.
