We are wondering what method / programs you use to analyze and design structural supports for Cantilever Overhead Sign Structures (COSS). Do you use STAAD.Pro to generate COSS models? What engineering codes are used in your country? See videos below for example:

You have posted your question in the French speaking community for MiroStation users.
I would recommend to post in in the same language as you are using, and relative to the same technical fieald to get more read and get more answers.
I have moved your question to the OpenRail Designer Community, please go back to me if you want another forum.
