Strand corrosion can cause the cracking of prestressed concrete. In this chapter, the concrete cracking caused by strand corrosion under different prestress is experimentally studied. Then, a theoretical model, incorporating the coupled effects of prestress and strand corrosion, is proposed to predict the global process of prestressed concrete cracking. Following this, a meso-scale numerical model is established to simulate concrete cracking induced by the three-dimensional corrosion expansion of helical strands.
