Loading tests were conducted to evaluate the structural behavior of connection panel, which consisted of connection between steel beam and high-strength concrete-filled circular tubular steel column. Elasto-plastic behavior of the connection panels were also analytically examined. This panel was modeled by superposing tri-linear relations for steel tube and filled concrete. For the latter component, the authors proposed to evaluate load resistance, in which a new theoretical arch mechanism was adopted in consideration of the confined effects of tube. The proposed analytical method was verified by examining preceding experimental results and those in this study, ranging from ordinary strengths to high strengths of steel and concrete. As a result, the analytical results proposed in this paper were found in agreement with the experimental results up to the maximum shearing capacity of concrete, although the analytical results tend to slightly underestimate the experimental results over the displacement range above the maximum shearing capacity of concrete.
