Hi all,
I'm doing hand calculations for a one storey braced building. I need to check the deflection of the building. To do so I've done what I thought was a simple hand check (attached).
However, I did a very quick check with STAAD just to make sure my hand calc was accurate but the deflection of the frame in STAAD comes out as exactly twice the deflection that I have calculated. I'm sure there's something very simple wrong with my hand calc but I can't see it myself. I don't want to use the results of STAAD without understanding them.
I would appreciate if one of you could have a quick look and let me know if you can see the issue with my hand calc.
Also, I see that the units for area are incorrect - supposed to be cm2!
Thank you very much
