| Abstract: | Post grouting concrete filled steel tube is ordinary technology in vertical bearing structures. Based on the experiment, this paper evaluated the mechanics performance of axial punching of post grouting concrete filled steel tube and summarized the various methods’ influences on the axial punching. By using experimental data and inverse analysis method, the related parameters for interface properties were obtained. This paper summed up the deformation characteristics of the post grouting connection between the original concrete columns and steel tube connection under the action of axial punching. Based on the experiment and numerical method, the post grouting connection method of interface was proposed, which provides a reference for future related projects. |
