Thanks for the feedback everyone. Seems like we're all on the same page and all questioning exactly what OSHA is referring to. Glad I'm not just missing the boat somehow.
I guess the other item I could argue to justify the "high" 1500 psi (assuming that's what they meant) reference would be...
Sorry if this has been asked and answered before, but I'm not finding it in any searches. I'm looking at fall protection requirements in OSHA Part 1926 and run into an appendix B which lists wood, pipe, and steel rail sections OSHA says meets their requirements for guardrail. Here's a link to...
Thanks for feedback. That said, I'd still argue that even API 5.7.4.2-4 never mentions the "reinforcing plate" and only indicates the requirements of these sections as being applicable to the shell, an insert plate, or a thickened insert plate? API's definitions for insert plate and thickened...
I'm hoping someone can help me out with some confusion I'm causing myself in regards to thermal stress relief for AWWA D100 water tanks. I'm working on a Section 14 tank with the bottom shell course over 1" thick (1.25" thick). I'm trying to figure out if the thermal stress relief requirements...
Yes, ideally there would be vents in the soffit. But, this roof is constructed w/ no rafter or truss tails extending beyond the exterior face of the walls (no overhang on the roof). So, the architect was hoping we could use the slots down low on the roof to provide the venting that would...
Thanks for the feedback everyone.
I told the architect I wasn't a huge fan and they are looking into alternatives. The slot would be along all perimeter edges of the roof and not at the ridge. The ridge already has a large steeple or cupola style vent, so no extra work needed there.
It's currently an unblocked diaphragm, so I suppose you're probably correct. Not all that much worse than the standard 1/8" gap the contractor is supposed to leave between all the sheathing edges to allow the sheets to swell if they get wet, etc. BUT, at the same time, if this was done as part...
I'm working on a renovation project for an existing wood framed building with plywood sheathed, hipped roofs throughout. The architect wants to improve the attic ventilation by having the roofing contractor install continuous "shingle over" style ventilation just inboard of the exterior walls...
Chris,
I would tend to agree w/ the others in your company. For a slab on grade I'd assume you're maintaining 3" clear to the bottom mat of steel. Then if you've got 4 layers of #4 bars (0.5" nominal, 0.56" outside width), the top mat of steel will be at best 1" below the top of the slab. In...
hokie66 and csd72, thanks for the advice. So, now I'm onto my next problem. I'm trying to put together hand calcs to verify a model developed by another engineer, and in the model, the force distribution is obviously somewhere between rigid and flexible diaphragm action. What I've got is a...
I'm looking for any information someone may have on determining the deflection, and more importantly the stiffness of a tilt up wall panel for an in-plane shear load. I'm currently working on a structure w/ 9" thick exterior, tilt-up, special reinforced concrete panels, and numerous interior...
