Behavior of prestressed concrete members under flexural loads and under fire is investigated in this research.  Prestressed concrete beams were subjected to fire experimentally and its behavior including its capacity and serviceability limit states were evaluated.  Moreover, prestressing concrete beams using carbon fiber reinforced tendons was also investigated.  Strengthening of flexural prestressed members was also investigated using fiber reinforced polymer laminates.  Design guidelines for concrete members whether externally or internally prestressed by FRP is introduced.
