Load cases - Wind
Hello everyone,
I don't really have a problem, but I wondered if there is a more elegant solution for this situation.
So, I've modeled a simple beam with Dead Load, Live Load, Snow Load acting on beam in Z+ direction and four cases of Wind load acting in both Z+ and Z- direction.
When RFEM generated combinations, every ULS combination had a 1.35 combination factor on Dead Load which is fine, but I don't know is there a way to make combinations(automatically) where Dead Load will have a 1.00 combination factor and Wind Loads will be multiplied with 1.50 (Dead load acts permanently on structure but it is unfavorable in those cases).
I'm not sure did I make everything clear, but the real purpose of this is to make maximum "negative" bending on a beam (or look for potential tension in the upper cord in trusses for example, etc.) caused by Wind forces.
To make everything clear. I'll upload a model where you can see Combinations: CO89, CO90, CO91, and CO92 which are created manually. Is there a way to make get them automatically along with other ULS combinations?
Just to mention, I am from Serbia and everything in this model is according to Eurocode.
I'm looking forward to your response!
Thanks in advance,
Dusan
