摘要：
To research the interfacial bond-slip behavior between a steel plate and high-strength concrete in shear walls, 10 steel plate-reinforced high-strength concrete shear wall (SPHSCSW) specimens with group studs were designed for push-out tests. The test parameters, such as the concrete strength, stud length-to-diameter ratio, and built-in tie bars were considered. The influence of different parameters on the bond-slip behavior of steel plate with studs and high-strength concrete was studied by analyzing the test load-slip curves and bond strength. The calculation formula for the shear capacity of studs in SPHSCSWs and the interfacial bond-slip constitutive relationship for different connectors were obtained. This study shows that the concrete strength and the bond strength of SPHSCSWs are positively correlated. When the length-to-diameter ratio of studs is greater than 4 and less than 8, the increase of the ratio has little effect on the improvement of the interfacial shear capacity. The residual bond strength of SPHSCSWs can be significantly improved by replacing part of the studs with tie bars. The calculated results of proposed fitting shear capacity calculation formula of studs in SPHSCSWs and the predicted curves of the bond-slip constitutive relationship agree well with the test results. They can thus be used as a reference for engineering applications. © 2021, Editorial Office of Journal of Building Structures. All right reserved.
