HTURKAK,
Thanks for the response. I agree with your first point. Your second point is where I've been getting stuck. Table 13.6-1 does not list coefficients for cranes nor do I see anything in 13.6 that references cranes. Perhaps cranes could be considered to fall under "other mechanical or...
If a chord that is only ever in tension has buckled, I agree the damage would have had to come from shipping or handling. You still have the same area of steel (unless it got chipped or gouged) and therefore the capacity is still the same.
Damaged compression chords are more difficult. You...
When determining the seismic load for a crane, is it more appropriate to use Chapter 12 or Chapter 13 of ASCE 7? Specifically, we are looking at the seismic force on the clips holding the rails, as well as the seismic lateral load on the crane beams (in this instance it's a bridge crane).
Haha. I think this is one that is often left unaddressed and we'd rather not know about. One of the many things that in real life often doesn't result in failure but we can never get to calculate out.
It would be nice if we could add rebar, and in the future that will be a talking point during...
I have often designed concrete-over-steel composite decks for floors. Recently, we have been receiving requests to attach handrails to the concrete, typically using expansion anchors or embed plates with headed studs. This creates a cantilever condition, which puts a portion of the concrete in...
The method used for determining MWFRS loads on an open building in ASCE 7-05 looks like it closely matches the method shown in Chapter 27 of ASCE 7-10, which would coincide with what both of you are suggesting. I think the user note in chapter 28 is incorrect and that chapter 27 ought to be...
In ASCE 7-10, should Chapter 27 or Chapter 28 be used to determine wind loads on an open low-rise building? I would prefer to use Chapter 28, but the title for Part 1 of Chapter 28 only indicates that it should be used for enclosed and partially enclosed low-rise buildings, but the user note in...
