To study the bond-slip behavior of interface between corrugated steel plate and concrete

ten corrugated steel plate-concrete specimens were designed for push-out test

considering concrete strength

concrete cover thickness

and embedded length of steel plate. The failure modes

stress mechanism

strain distribution

bond strength

and bond-slip constitutive relations of the specimens were studied. Test results show that bond splitting failure and bond anchorage failure mainly occurred in the corrugated steel plate-concrete composite members. The load-slip curve could be divided into micro-slip stage

slip stage

steep-drop stage

gentle-drop stage

and residual stage. At the load rising stage

the strain of the corrugated steel plate distributed exponentially along the embedded length

and the phenomenon of zero-point crossing of strain might occur at the free end of the steel plate. By analyzing the influences of concrete strength

concrete cover thickness

and embedded length of steel plate on the bond strength of interface between corrugated steel plate and concrete

the calculation formulas of characteristic bond strength were fitted linearly

and the error between theoretical values and test results was small. Based on the bond-slip constitutive model of interface between corrugated steel plate and concrete

typical specimens were simulated by using ABAQUS software

and the curves of finite element model were in good agreement with test results.
