Advance in Researches on Bond Behavior for Steel-Corroded Concrete Members
摘要
Abstract
The steel corrosion in concrete is widely reported over the last two to three decades. Much effort has been devoted to researching the causes and mechanisms of reinforcement corrosion and to the questions of durability for concrete structures, but relatively little attention has been devoted to the problem of assessing the effect of bond loss due to corrosion on the structural behavior of corroded elements. From the test results on corroded specimens, the mechanism of degradation in bond behavior between corroded bars and concrete, and the effects of bond loss on structural performances are summarized. Results show that corrosion level, cover depth-to-bar diameter ratio, surface condition of reinforcement, stirrups, etc. can influence the bond behavior of corroded bars. In addition, the deterioration in bond due to corrosion may induce reduction in bearing capacity, degradation of serviceability, and the loss in ductility for steel-corroded concrete members.关键词
