Steel design interaction factors

Hi,

For the same member I have the following design ratios, the member is a CHS with compression and bending.

Column - Method 1 interaction factor, design ratio = 1.15

Simple bar - Method 1 interaction factor, design ratio = 1.85

Column - Method 2 interaction factor, design ratio = 1.95

Simple bar - Method 2 interaction factor, design ratio = 1.95

Does anyone know why is there is such a difference under method 1 for different bar types?

Could you attach the model please.

Sorry, that query was 14 months ago. I have had a look and cannot find the model.
