Thanks, everyone, for many helpful tips & discussion.
One other question...considering 2000 IBC loads (table 1607.1), I'm applying 100 psf live load to the running track. The 100psf LL equates to 1400+/- really big persons (250lb) on the track. I realize that with running, impact forces are...
COEngineer - yeah, actually 42psf snow, but that's correct. Live load on the track will cause some deflection, and snow load on the roof will cause some deflection.
Lutfi - You read correctly, joists are at 12'oc. I'll be using 3", 18 gage deck. Per your other comment, the cumulative deflection is what concerns me - a small deflection for the joist is not small for the running track.
Hello,
I've got a 120'x108' gymnasium. The roof joists span 108'. There is also a 10' wide running track on the inside perimeter of the gym hung from the joists every 21'-8" to 24'. The joists are spaced at 12'o.c., with each end where the track is parallel with the joists, the joists are...
We just got the 5th edition of the Timber Construction Manual - which points back to 4th edition for & some AITC tech-notes for analysis. Seems my original search wasn't as comprehensive as I thought... ;-)
As mrengineer mentioned, I'll most likely be deferring the final design to the glu-lam...
I'm doing schematic design to determine approximate member size of a curved (140' radius) glu-lam wood arch. The base dimensions are approximately 185' width about a 35' rise at mid-span. These arches are spaced 10' to 12' o.c. to form a shelter roof for an outdoor stage.
I've turned up very...
Hello,
I've come up with a couple of options for a roof based on diaphragm capacities for SDI deck (using 5/8" puddle weld & #10 sidelap fasteners) The table below indicates for each deck type & weld pattern, how many sidelaps fasteners I would use...
Deck Type 36/5 36/7
