摘要：
In order to study the fatigue behavior of steel-concrete composite beams with corroded stubs under negative bending moment, one specimen was tested under static loading while five specimens were tested under fatigue loading. In the static test, the bearing capacity of the composite beam under negative bending moment was obtained as a reference for the fatigue tests. In the fatigue tests, the load-strain curves, load-mid span deflection curves, the residual deformation and stiffness were obtained. The test results indicate that the fatigue life of test specimens decreases with the increases of corrosion rate of studs while the residual deformation increases with the increases of corrosion rate of studs. The stiffness of test specimens decreases during the fatigue loading process but has no relationship with the corrosion rates. The slip stiffness decreases significantly with the increases of corrosion rate of the studs. © 2019, Editorial Office of Journal of Building Structures. All right reserved.
