Abstract：A series of pushout tests were carried out for the bond mechanism, bond strength and bondslip constitutive relations between corrugated steel plate and concreteEight pushout specimens are designed to study the influences of wave angle and length of wave trough on bondslip behavior, and the bonding properties at wave angle, wave ridge and wave trough are investigatedThe experimental results indicate that, for specimens with the same size of wave trough and wave ridge, bond strength of the obtuse angle specimen increases with the increase of the wave angle; the bond strength of the acute angle specimen decreases with the increase of wave angleIn addition, for the waveforms with the same wave angle, the bond strength decreases with the increase of wave troughIn the microslip phase and the sliding phase, the strain of the corrugated steel plate is exponentially distributed along the embedment lengthThe strains at the wave ridge and the wave angle are greater than that at the axis of wave troughDuring the failure stage, the load descent stage and the residual stage, the strain distribution of the corrugated steel plate is complex, and zero crossing phenomenon may appear along the embedment lengthAccording to the experimental loadslip curves at loadend and freeend of all specimens, the calculation formulas of characteristic bond strength are established by statistical regressionBy establishing the equilibrium equation of mechanics, it is found that the bond stress of the corrugated steel sheet is distributed exponentially along the embedment depth, and furthermore, a bond slip constitutive model considering the position function is establishedBased on the finite element software ANSYS, numerical simulations were conducted for the specimens considering the bondslip constitutive relation and the bondslip constitutive relation of the position functionThe results show that the bondslip constitutive relation considering the position function shall be more accurate.
