6. Conclusion
The procedure according to EN 1994-1-1 to check the strength of composite columns, subjected to compression and uniaxial or biaxial bending, may appear relatively complex to a designer, compared to steel columns alone.
Indeed, as in the EN 1993-1-1 In clause 6.3.3, we provide formulas for the interaction between compression force and bending moments, facilitating direct verification in the member's local reference frame to prevent form instability.
A first difficulty encountered with composite columns was the complexity of the phenomena governing concrete behavior, in particular the effects of creep and shrinkage. However, as these effects only need to be considered in practice...
