reaction values for metal building structure
reaction values for metal building structure
(OP)
hello,
I am working on the foundation design for a metal building. I was given the basic column reactions (unfactored) and i am not clear on what the different categories are and there is no explanation or definition provided. I have a feeling it is obvious and my brain is just not cooperating. Reactions are given for each of the following: dead, collateral, live, snow, wind_left1, wind_right1, wind_left2, wind_right2, wind_long1, wind_long2 and then seismic and min. snow and unbalanced snow. can anyone explain what the 1 and 2 are with respect to the wind values are? I am not sure if it is referring to different cases in ASCE 7-10 or what.
I appreciate the help.

I would almost say it's intentionally confusing to reduce their liability. That way if there's a problem, they can say "you misapplied the loads it's your fault."
Combine that with the fact that they won't design their own anchorage to the concrete and it makes me not want to use these buildings. I campaign against them when I can, but sometimes lose.
When we get the same kind of loads, we prepare an excel spreadsheet and combine them the best we can, using the ASCE 7 load factors.
