Numerical Simulation of Retraction Effect of Corroded Prestressed Steel Strands Based on Cohesive Contact
XU Dejun, LI Jun, Yi Jiafei, ZHANG Xiangzhen et autres
Concrete cracking and bond degradation caused by corrosion lead to retraction slip of prestressed steel strands and changes in transfer length. Simulating the retraction effect of corroded prestressed steel strands is a difficulty in current research. A numerical model for corroded prestressed …
