The present study analyzes the flexure behavior of the circular CFT member through experiment and numerical analysis. Through comparison between experimental and numerical results, whether or not the member was a full composite have little effect on the behavior. There circular CFT’s flexure behavior when considering pure moment is almost similar regardless of the interface characteristics between the steel and concrete. This is because there is no difference in the neutral axis of the full-composite and non-composite circular CFT member.

Two types of connection between the abutment and CFT pile were proposed for the sub-structure of the integral abutment bridge. One was a bolt connection (Type-A) and the other was a hook connection (Type-B). To analyze the performance of connection Type-A and Type-B, a quasi-static experiment was carried out. According to experimental results, the destruction occurred at the connection point and so both type A and type B need to have a reinforced design as the link between the abutment and CFT pile. However, when the load resistance performance and energy dissipation capacity was analyzed, the performance of connection Type-B was superior to the performance of connection Type-A.

In this study, a quasi-static experiment was conducted on the connection performance between the integral abutment bridge and CFT pile. Six experiment specimen were manufactured and were divided into type A and type B. Experiment specimens of Type A were connected with bolts and experiment specimens of Type B were connected with hooks. In the experiment results the connection performance of Type B showed excellent performance more than that of Type A.

In this study, we study the behavior of CFT subjected to pure bending moment considering the interface character between the materials. We assume that the interface between the materials has 2 cases, one is full-composite the other is non-composite. Through the analysis of the FEM results, we find that CFT’s flexure behavior is unique compared to other composite structures. There is almost similar CFT’s flexure behavior in the pure moment regardless of interface character between steel and concrete. This is because there is no difference in the neutral axis of the full-composite and non-composite in the CFT scetion.
