Abstract

AbstractCorrosion can reduce the sectional area of strand, induce concrete cracking, and degrade bond strength, which can further decrease the bearing capacity of prestressed concrete beams. First, an analytical model is proposed to predict the flexural bearing capacity of partially ungrouted post-tensioned concrete beams. Then, a prediction model of corroded prestressed concrete beams is established to calculate the incompatible deformation between strand and concrete under different load conditions.
