Bond-slip properties of corrugated steel plate-rubber interface

Due to the geometric advantages of corrugated steel plates, corrugated steel plates-rubber members exhibit good seismic performance. The bond-slip property of their interface requires investigation. To study the interface properties of corrugated steel plate and rubber, 6 specimens were designed for reciprocal loading tests, considering bonding length, roughness, and loading mode effects. Analysis of the specimens' bonding properties involve examining bonding failure processes, interfacial energy dissipation, strain distribution and influencing factors. Results indicate that under reciprocal loads, bonding failure progresses through micro-slip, slip, failure, curve decline and residual stages. Energy analysis reveals that the bond length's magnitude significantly affects the interfacial energy dissipation. Reasonable control of roughness can improve the specimen interfacial energy dissipation and improve the interfacial bonding performance. High loads on corrugated steel plates and rubber members cause abrupt strain changes, with the wave ridge experiencing the most significant impact. Residual bond slip under reciprocal loading is 29% lower than under monotone loading. The ultimate characteristic bond strength of the corrugated steel plate-rubber specimens shows an increase and then a gradual decrease with the increase of bond length and roughness; Formulas for calculating characteristic bond strength for these members are established, with calculated values compared to experimental results showing a good coincidence.
