锈蚀钢筋混凝土黏结性能及本构关系的试验研究
Experimental Research on Bond Behavior and Bond Stress-slip Relationship between Corroded Steel Bars and Concrete
摘要
Abstract
The bond-slip curves between high strength reinforcing bars and concrete with reinforcement mass loss percentage ranged from 0 to 4.84% was studied by electro-chemistry method.The effect of corrosion ratio on bond strength as well as bond stiffness between high strength reinforcing bar and concrete were analyzed.The experimental results indicated that the bond strength as well as bond stiffness between high strength reinforcing bars and concrete increases with increasing corrosion ratio when corrosion percentage is below 2.22%,and then decreases when corrosion percentage exceed 3.46%.Based on the test results,the bond-slip constitutive equation with considered the influence of corrosion is proposed,which can be used in finite element analysis of corroded reinforced-concrete.关键词
