다국어 초록 (Multilingual Abstract)

The purpose of this study is to clarify on local tensile strength of connection with external ring stiffener between beam and Concrete-Filled Circular Tube(CFT) Column. Two kinds of failure modes are represented in CFT beam-column connections with an exterior ring stiffener. The first mode is a local tensile failure of a stiffener ring. The second mode is a steel beam flange failure. Based on failure modes, a local tensile strengths of connection with stiffener ring can be evaluated and an equation to predict a local strength is suggested in this study. The equation is verified through a comparison between an equation and test results.
