Composite Steel Column to EC4 Using Excel & Calc

Composite Column Design to EC4 (Excel & Calc) - The spreadsheet program can design and check the rectangular concrete column with steel I-section, Concrete filled circular section (CHS) and Concrete filled rectangular section (RHS & SHS ).

A screenshot of the rectangular concrete column with steel I-section is show below:

Reinforcement can also be added to the section. Moment capacity check and interaction ratio check according to EC4 will also be carried out.

Similarly, the program can also carried out concrete filled circular section CHS, rectangular section RHS and square section SHS.

The excel and calc spreadsheet were tested using examples and also compared with the EC4 capacity tables listed in the handbook. The results are exact and proved to be accurate.

For the same Excel and Calc spreadsheet, section capacity check for steel section subject to axial force, bending moment and shear force are also included. The section check is applicable to UB or UC section with fully restraint or non-restraint conditions. User will need to input the restraint length to calculate the buckling moment capacity.


  1. This is excellent works !

  2. it would be great if you can email me a copy of your spread sheet to

    Many Thanks

  3. it would be a great support for my design project because of lack of the information about Composite column in internet,
    please email me a copy of your spread sheet to

    Best Regards,

  4. really appreciate if you can send me a copy over to
    Best wishes

  5. Could you send it for me too? it will be very interesting for my studies.

  6. Great if you can email the EC RC and composite column to EC 4 to me at

    A great thanks


  7. Can you send it for me and my email is

    Thanks with Regards,

  8. hi we are an engineering company in Australia, this would be extremely useful for us, can you email it to we can make a donation if required. Thanks

  9. Could you send it for me too?

  10. Hi, we are engineering company in Malaysia, it will be great that you will email it to thanks

  11. Hi,
