Interface Behavior between Steel and Concrete Connected by Bonding
Publication: Journal of Bridge Engineering
Volume 21, Issue 6
Abstract
In this study, push-out tests were conducted to evaluate the interface behavior between steel and concrete connected by bonding. Twelve sets of specimens with different adhesive thicknesses, modulus of elasticity, and interface roughness were investigated. Failure modes, ultimate loads, and load–slip relationships are reported and analyzed in the paper. The experimental results show that factors such as modulus of elasticity of adhesive materials, adhesive thickness, and interface roughness affect the interface behavior. An analytical model is proposed to predict the ultimate load value and the load–slip relationship. The comparison between test results and analytical predictions shows good agreement.
