摘要：

The effective length of concrete filled steel tubular (CFST) frame columns is a key parameter to determine its ultimate strength for engineering design. There was no special design code, so engineers usually got the values according with specification for steel structure. This may cause error in some degree. Based on liner and non-linear buckling analysis respectively, the overall stability of a typical planar composite frame with CFST columns and steel beams was performed in this paper. By comparing the results of finite element method with current approach, some primary conclusions were given to refer for engineering practice on the composite frames.
