Concrete cracking caused by strand corrosion reduces bond strength and leads to loss of prestress and changes in transfer length. In this chapter, a model, considering the coupled effects of concrete cracking and bond degradation, is proposed to predict the corrosion-induced prestress loss in prestressed concrete structures at first. Then, an analytical model, considering the coupled effects of the Hoyer effect and corrosion-induced cracking, is proposed to predict the transfer length. The effects of strand corrosion on the effective prestress and transfer length are studied.
