Incorrect sections, unrealistic utilisation ratios

Anonymous — Tue, 09 Feb 2021 05:17:12 GMT

I have beams which are restrained by rafters and connecting beams and am having countless errors despite a carefully constructed model. I have been working on this model for countless hours and still not making progress.

Also how do I ensure that the beams are laterally braced?

Regards

Job

HI @Anonymous ,

Hard to see without jumping in to your model. Can you upload your model to share?

It seems the lateral torsional buckling of members is giving the wrong results. For a start the members are loaded vertically. When I check the detailed calculations, they are coming out with axial forces and am not sure where they are coming from.

can you please advise on how to upload model? The last time I tried it was rejected.
