Turns out these tees are good for 82 PSF superimposed load. I don't have a table for composite, which I believe these are, so at least it's conservative. Let me know if you want a copy of the table.
I knew what you meant Jed. Interesting idea, thank you. It seems possible though that the concrete controls and using the design load for an 8' wide tee would not be conservative. The span on these is 80'.
Assuming an 8' wide tee, these would have a live load capacity of 41 PSF. That seems...
I'm trying to determine the allowable load on precast single tee's from 1971, the designation is 6T 36L-14.8. They have a 2" topping but the original drawings do not indicate whether it was composite or not.
The First Edition PCI Design Handbook (1971) doesn't cover 6' wide tee's. Any help...
I had a project several years ago with the same scenario but a 50' span. I don't have my calcs anymore but a quick stab at it give me about 2.5 kips/ft and I had an 11' deep truss w/ W8x58 chords. The top chord was near the auditorium roof and was braced by the roof deck. The truss is firred...
Camber in precast plank is a result of the manufacturing process, prestressing force causes the camber. It is not designed in.

Civilperson you must be specifying 2" minimum topping? Otherwise you will not get 2" due to camber in the plank (not necessarily differences in camber). I'm assuming topping is poured level.
I only use WWF if the topping is 4" thick (nominal). Any thinner and it's too difficult to place. Otherwise I only use fiber. Yes the topping slab is the diaphragm, use a bar centered in the slab at the perimeter.
As far as it being for composite action, when you consider the camber in the...
I have found masons in the same geographical area that treat bond beams differently at the control joints, some will grease the bars so they will slip, some will stop them, and some will run the bars through. We use them as diaphragm chords but we have a detail that shows to stop the control...
Edge distance refers to the edge (end or top) of the wall.
If all the cores are grouted solid it does not make any difference if the anchor is placed in the mortar joint.
I have a school that is just being completed where I designed 100' long, 17' deep bowstring trusses (depth was an esthetic issue, not structural). Construction bridging was by the fabricator and erector, and final bridging was two lines of angles on top of the bottom chords. The connections...
I'm not sure what you mean by the beam flange exceeding the maximum possible plate width, your plate size should be determined by the allowable bearing stress and the beam reaction.
I assume you are referring to a beam bearing on CMU but I suppose concrete would not be any different. A 1" thick...
