I am performing a check of lateral buckling of a beam according to Eurocode 3. With the detailed method, 6.3.2.3 the factors C1-C3 are showing up in the detailed results. The reference is to ENV311 F1.... which is a code that I am not familiar with. I am having some doubts as to the validity of my code check and would like to control the C1-C3 values, but I am unable to do so since I don't have the afforementioned ENV code. Could someone give me a hint as to how to check these values?
I am getting a lot smaller XLT in Robot, compared to when I am doing it by hand.
edit: attached some info. It is a continuous IPE270 beam.
No you can´t change the C factors manually, only by changing load level and load type in member definition dialog Robot will define these factors according to annex F tables.
In RSA 2014 there is also possibility to insert your own Mcr for the member.
I see. I wanted to track Robots way of finding these factors, which then seems impossible without the annex F.
I have added the request for manual definition of Cs values to the wish list for next versions of Robot.
