Elasto-plastic behaviour of two types of connection between concrete filled steel tubular column and beam flange, unstiffened type and reinforced by increasing the column thickness at the connection area type (Long-stiffher type), have been investigated by experiment and FEM analysis. The estimation formulas of the local yield and ultimate strengths of unstiffened and long-stiffner types of connection between concrete filled tubular steel columns and beam flange are proposed based on the yield line theory, which takes into account of the influence of axial load ratio on column. The estimated local yield and ultimate strengths are generally giving good correspondence with the experimental as well as FEM analysis results.
