Hello,
I have a STAAD code which is a simple beam design with loads and I was doing steel design. On performing design I got the results of beam unity check to be 0.74 (Actual Ratio). But on double clicking the beam and then going to Steel Design Section I see Unity check to be 0.41. This is weird. Can someone please give me an explanation on this. Uploaded the image and STAAD Code. I am using STAAD.Pro V8i (SELECTseries 6) 20.07.11.33
Thanks,
