Reaching out to see if anyone has any references to determine the weight of an old 600 HP, 2300V, 151A, 3 Phase Westinghouse synchronous motor. I've contacted various sources at Westinghouse (or their related company today), done a reasonable amount of web searching and have had no luck...
Section is definitely not HSS. I'm thinking it was a custom built-up riveted section detailed on a drawing long discarded. I was hoping someone else may have run across the designation previous.
I suppose as a side discussion, there is a mis-conception that Canada exclusively uses the metric...
Good day. I'm looking for some help on determining a reference for the historical steel shape 16x12BR110 as noted in the subject line. I've come across it from a circa 1953 steel drawing from Canada and the BR is stumping me. Going to the usual sources (AISC, CISC, Bethelehem Steel) I can't...
Does anyone know of a reference that accounts for radiant heating tubes in unreinforced slab on grade design? I'll have 1/2" diameter tubes with 2" cover, but I haven't yet found good information on accounting for them in the structural design.
Yes, a great deal of them are. I did some finite element plate analysis for Cases 1-3, and the ones I did came out elastic.
My design case was for Case 9 with and length aspect ratio of 0.85. The 0.072 is about 1/2 of what you get with elastic analysis.
I'm past the engineering phase of...
I'm trying to get some background information on the tables for two-way slab design (with rigid edge supports) in the Canadian concrete code. I've been searching the usual journal for a direct reference but have come up empty.
Does anyone understand the historical development of these...
I'm working on a project which requires a new grain chute to direct grain from a height of about 65'. The grain comes from a ship-unloader and is dumped through a roof hatch of an existing grain storage building.
My question is, what is a good reference for such a chute design? Any suggestions?
I'm working on a grain storage/retaining wall problem. I'm dropping soya and canola from approximately 65' above ground level and designing a retaining wall at several locations.
What I'm looking for is a good reference for the angle of repose, angle of internal friction, and the effect of the...
Taking the passive pressure into account is not good practice in cases like this. The deflection required to develop the passive pressure force would be in the order of inches. This would mean a deflection at the top of the pier of 3+ inches.
If this were a retaining wall, you'd of course...
I'm working on a pre-eng building foundation where the columns will rest on piers 8' about the finished floor. The footings are founded at 5'6 below the finished floor. The span of each building frame is 145' and the shear loads are very high.
One option I seen used is to tie the pier to...
20 psf is less than 1 kPa in SI, which is typical in some cases but low in terms of lateral load failure. Is this a URM section? Have you considered 8'' block with a little reinforcement?
More and more there is less call for cavity walls, just veneer with a block backup with the backup...
