RE: Staad loading

[Subject Prev][Subject Next][Thread Prev][Thread Next]

John and Randy,

 

Thanks for the reply.

Randy, it does appear that the units are feet and kips.  Earlier in the printout there is a line which states UNIT FEET KIPS.

 

Thanks,

 

Joe

Joe,

Your assumption looks correct, but I would also check the units to make sure he specified kips and feet, just to be sure. I can take a quick look at it if you care to send it to me privately.

 

Regards,

 

Randall H. Collier, P.E.

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 don’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 24” 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 LOAD

44. MEMBER LOAD

45 3 UNI GY -.08

 

I’m assuming that this is a 40 psf live load at 2’ centers which is 80 plf or .08 klf.  I’m pretty sure that is right, but just checking.

 

Thanks,

Joseph R. Grill, PE
