| Abstract | ||||
| The objective of this study is to investigate the difference between three approaches used for the design of concrete encased composite columns. The first approach "ECP-SCLRFD [1]" considers the composite column as an equivalent to steel section, the second "Eurocode 4 [2] and AISC [3]" considers the composite column as composite section using rigid plastic stress distribution, and the third "ACI [4] and CSA [5]" is similar to second approach with elastic plastic stress distribution. The comparative study indicates that the second and third approach give good results for composite columns strength compared with the first approach according to physical test results done by previous researchers. Also, this paper suggested a proposed formula for interaction equation for composite columns. | ||||
