A lot of concrete filled steel tubular (CFT) columns subjected to axial compressive load and bending moment have been tested in Japan. It has become clear that CFT columns have many excellent structural properties, such as high compressive strength, large ductility and large energy absorption capacity. Database for maximum bending strength Mmax are produced on the basis of experimental works which were performed in Japan. Theoretical strength Mpc is calculated assuming full plastic stress distribution. The nondimensional strength Mmax/Mpc are examined and discussed in accordance with several parameters such as width (diameter) - thickness ratio of steel tube, axial load ratio, shear span ratio, strength of material and loading condition.
