Sounds right... confirm the units by scrolling up the output list to the most recent line stating "UNIT KIPS FEET". If it says otherwise, well....

It appears from what youâ??ve listed below that your colleague has specified a uniform load of -.08 kip/ft (.040 ksf X 2 ft) on member #3 in the global Y direction (negative)â?¦looks like you have 40 psf loading on a trib of 2â??â?¦
Hope this helps.

A quick question for you staad fans, and probably a very easy one at that.An engineer in one of our other offices is out on vacation. He uses staad, where I donâ??t. Anyway, a client of his has a question on some work he did, which I only have to verify the loading on the bottom chord of a truss. The truss is a light pre-manufactured wood roof truss over a garage with an attic space. The truss is going to be altered slightly and are at 24â?? spacing. The client wishes to confirm that a 40psf load was used for the lower chord of the trusses.I got the file from their office which included the staad output. He used a load at the bottom chord as follows:43. LOAD 3 FLOOR LIVE LOAD44. MEMBER LOAD45 3 UNI GY -.08Iâ??m assuming that this is a 40 psf live load at 2â?? centers which is 80 plf or .08 klf. Iâ??m pretty sure that is right, but just checking.Thanks,Joseph R. Grill, PE
