Residual deflection analysis in negative moment regions of steel-concrete composite beams under fatigue loading

This paper presents the results of an experimental and analytical study on the residual deflection behavior in the negative moment regions of steel-concrete composite beams under fatigue loading. Firstly, fatigue tests with different load amplitudes were performed on two steel-concrete composite plate beam specimens subjected to negative moment. The residual values of slip and deflection at the interval time of the loading procedure were...
