If WT's are cut from WF's then they need to be straightened. There are residual stresses in them that cause them to warp. Some fabricators just would rather buy them from a supplier then deal with straightening them. Best way to determine premium is to get a quote from a local fabricator.
You might want to contact your insurance underwriter to find out their advice. Are these the original design drawings or as built drawings? A stamp on each drawing stating what they are and what they are based upon at a minimum is very important. For instance, as built drawings are often based...
Any recommendations on a good quality, commercial grade, spray-on brick waterproofer? Must be waterproof, breathable and not affect color. Prefer 10 to 15 year guarantee.
Looks like some kind of cold rolled members. The Architect should know that you need more info than pictures especially if you are making modifications.
Need to measure web depth and thickness, flange configuration and thickness and member spacing. Is there any drawings available from Owner or...
Before developing any kind of detail, you must calculate the loads that need to be transferred. For example: lateral wind load on wall, seismic load on wall, load being transferred from hollow core plank to shear wall, etc.
If loads are small then don't forget to apply minimum requirements...
Another consideration is if you are bonding the plate directly to the concrete (and using the bolts only to hold the plate in place until the epoxy cures) then you better find out how the epoxy may be affected by moisture and/or fire. If you have a fire rating, you may not be able to use a...
A couple of considerations/comments:
1) If the slab has a fire rating then the steel plates may need to have sprayed on fireproofing.
2) Make sure that the holes are NOT oversized so that the bolts can bear against the steel so the load can get transferred without slippage. Alternates may be a)...
Although I have been retired for 5+ years, I recommend the book "Designing Floor Slabs on Grade" by Boyd C. Ringo and Robert B. Anderson. It was published by CRSI. I believe you can download a pdf version if you search the internet.
The critical bending for a uniform load such as you have is...
There are a two other mechanisms that might be working to provide stability.
1) Commonly concrete slabs were formed with wood running to the bottom of the top flange of beams. This would leave a lip of concrete that can bear against the top flange of beams.
2) Also concrete was usually...
I believe there is a square inch requirement per anchor in the code (I don't remember what it is however), therefore if the 16" oc doesn't work with the stone, as long as you meet the code requirement.
I would also opt for half as many joints (about every 20 feet). I would also agree on eliminating the joints at the walls and instead dowel into them. Eliminate holes in forms by using threaded rebar inserts or by drilling and epoxying the dowels.
Another suggestion might be to eliminate the...
Is there enough strength in the precast roof to rig directly off of? If not, can you install the elevator beam above the roof and rig to it thru a hole in the precast roof? Architect will probably insist that beam above the roof be removed after installation and before roofing installation...
This structure looks like it might have been exposed to fire or at least heavy smoke or soot.
The mesh was for the plaster that was applied to the bottom of the deck for (I guess) is fire protection. At your description, I thought it might have been a keystone deck but looking at the photo, I...
