探讨埋入式柱脚压弯状态下型钢与混凝土的粘结滑移性能。通过自行研制的内置式型钢-混凝土电子滑移传感器对内部滑移进行了测量,解决了型钢混凝土粘结滑移试验研究的一个难题。基于试验结果,得到考虑界面正应力影响的型钢-混凝土的粘结滑移关系,为型钢混凝土受力变形全过程数值分析提供了本构模型。

This paper discusses the bond-slip behaviors between the structural steel and concrete when the embedded column base is in bending state.A self-developed embedded electronic steel-concrete slip transfer was used to measure the local slip,and a most difficult problem in the experimental research of the steel-concrete bond-slip was consequently solved.Based on the results of the experiment,the steel-concrete bond-slip relation concerning the influence of the normal stress was obtained,which can provide the constitutive model for the whole numerical analysis of the steel reinforced concrete deformation.
