According to code nomeclature all walls have to be at least 80% open to be classified as an open stucture. Due to the...
I have the original shop drawings calling out Z-purlins. The drawings however do not call out the strength or gauge, but based on the thickness called out (0.064-0.069in) and the moment of inertia about the x-x axis (13.87 in^4 calc'd from cross-section dimensions) I would say it is either 14-16...
Does anyone know what the standard strength for Z-pulins in 1982 was? 33ksi or 55ksi?
Any info on moment capacity tables for different sizes would also be helpful.
Thanks
I am designing the mount brackets to mount solar panels on a roof. I have calculated the pullout force to be 1260 lbs per bolt and can only use 2 bolts (i.e. total pullout from wind load is 2520 lbs). The bolts are to be 1/4" and mounted in Doug-Fir wood. This means I would need 5.5 inches of...
Can anyone out there tell me what the live load (uniform and concentrated) is for passenger vehicle type parking garages per the 1976 UBC. The oldest UBC we have in my office is 1988, which calls out a 50-psf uniform load and concentrated wheel load of not less than 2000 pounds without uniform...

Has anyone ever heard of a W14x17.2?

I was wondering if this was a shape that used to be available or if anyone has an input on what is being called out please let me know.
I have attached...
