Theoretical model to determine bond loss in prestressed concrete with reinforcement corrosion
Ortega, Nestor F.,Moro, Juan M.,Meneses, Romina S. Techno-Press 2018 Structural Engineering and Mechanics, An Int'l Jou Vol.65 No.1
This paper reviews the mechanical effects produced by reinforcement corrosion of prestressed concrete beams. Specifically, modifications in the bonding of the tendon to the concrete that reduce service life and load bearing capacity are studied. Experimental information gathered from previous works has been used for the theoretical analysis. Relationships between bond stress loss and reinforcement penetration in the concrete, and concrete external cracking were established. Also, it was analysed the influence that has the location of the area affected by corrosion on the loss magnitude of the initial prestress.
