Abstract
CFT(Concrete-Filled Tube) structures have problems at processing cause closed section and concrete filling problems. In this study, a CFT structure that uses different types of diaphragms in its upper and lower connections to improve the concrete filling was tested and analyzed via the FEM program. Implementation of variable analysis of EP-T type to find out the reason that effect on the resistance force of the connection. As a result, through experiments and analysis investigated the structural characteristics of circular CFT beam-to-column connection.
