This report represents structural characteristics of the concrete-filled square tubular section with inner ribs height of which is 3 mm in average. The concrete-filled square tubular section columns have many advantages in structural characteristics and in construction methods. However, the uncertainties in the strength of filled concrete and in stress transfer mechanism to filled concrete are pointed out. These are the reasons why this column is not popular so far in Japan. In this research , these problems are tried to be solved by improvement of bond stress capacity between steel surface and filled concrete. Results of the Beam-Column experiments indicate that the completely composite sections are available by using the square tubular sections with inner ribs, and the sections have sufficient ability on strength and deformation capacity, even if the width-thickness ratio and the axial load are rather large.
