Flexural Strength and Deformation Capacity of PC Members with Combined Bonded and Unbonded Steel or CFRP Tendons

Abstract

Abstract Some potential applications where bonded steel or carbon fiber–reinforced polymer (CFRP) tendons are combined with unbonded tendons are in the staged construction of prestressed concrete (PC) members and when strengthening existing PC members ... Practical Applications The design-oriented approach, together with the ductility expressions derived in this study, allows designers to directly evaluate the ultimate flexural design characteristics of concrete members prestressed using a combination of ...
