【Abstract】 The calculation methods of bearing capacity of concrete filled steel tubular columns’ under eccentrically loading and calculated methods are discussed. Taking two group of concrete filled steel tubular column as examples, the bearing capacity of the columns with the slenderness ratios from 3 to 20 is calculated. Columns are unit columns and their eccentricity increase step by step. The calculated results of bearing capacity of eccentrically\|loaded concrete filled steel tubular columns are compared and analyzed. Results show that the difference of the calculated results by three calculation methods is small, at the large slenderness ratio. Otherwise , the influence of slenderness ratios and eccentricity rations to bearing capacity is large.更多还原
