@transmissiontowers,
Thanks for the update, I completely agree with cutting substation costs! Stop complaining about using a W12 column when the circuit breakers cost 10X the value!! I just got done analyzing a huge lattice structure in California, only to hear the client complain "well it's...
Transmissiontowers, that's actually another debated opinion in our group; the exemption in ASCE for transmission and whether or not it applies to substation structures and foundations. I believe the exemption does apply for wire supporting tline towers, but not necessarily heavy 1million lb...
Dauwerda - I've used those, specifically the strut and tie paper you linked. They are useful, but I suppose the question remains how to treat round ties as supplemental shear reinforcement. IMO, the shear ties confine the concrete cone from breaking out, but I still haven't found a good...
Again, that is for all the info and insight, Transmissiontowers! I would love it if you were correct and the industry segregated from ASCE 7 and just used its own wind loading. Far too often than not, I have a client who's standards use ASCE 7-05, State building code uses 7-10, and NESC also...
My instinct would be to follow ASCE 74 and/or ASCE 7-16... Following NESC now is so out of date, and as you stated, just a safety code, not code. I think using a 200-year MRI would be reasonable for ultimate design, alone with a 25 yr MRI for deflection. Thanks @Transmissiontowers for keeping us...
