Analytical Models of Local Concrete‐Steel Bond at Low Temperature
Publication: Journal of Cold Regions Engineering
Volume 3, Issue 4
Abstract
Analytical models of local bond stress‐slip relationships are established based on an experimental program of 65 specimens in the temperature range between and and at normal temperature One can conclude that low temperature has little influence on the relationship between concrete compressive strength, and the maximum bond stress, as well as bond behavior, except that an increase in compressive strength is associated with an increase in bond strength. An analytical model for cyclic loading is established by estimating the deterioration of bond resistance and reloading stiffness. The deterioration appears to be closely related to the effective energy dissipated during the loading cycles. This analytical model has been applied to describe the bond stress‐slip relationship of the concrete‐steel interface under monotonic, repeated‐cyclic, and reversed‐cyclic loading conditions. Very good correlations between the numerical predictions and the experimental results were obtained.
