Abstract

To study the influence of steel strands corrosion on the long-term behavior of bond-creep,6 pre-tensioned prestressed concrete beams were fabricated,of which,5 beams were mixed with salt and set in different places to be corroded in different intensity for 47 weeks,and the bond-slip of all the 6 beams was tested periodically through the whole period,and then the time varying curves of bond-slip under prestressing were obtained.The results show that under the condition of no corrosion crack,the bond strength increases with corrosion and the bond-creep is restrained,which contribute the creep slip of corrosion beams being less than that of the uncorrosion beam.Moreover,with the increase of corrosion rate and corrosion products expansion ratio,the long-term bond-slip decreases.The analysis shows that if there are corrosion cracks and the bond strength deteriorates,the long-term bond-creep and the load cracks width in anchoring segments should increase,but the prestressing loss and the anchoring bearing capacity should not decrease.
