I was working on a portal frame and I need to design this type of apex haunch on staad pro or ram connection
pictures attached below
Are you talking about the bottom, haunch portion of the section? That can be from a wide flange, WT etc:
Yes. I've managed to figure it out. Apparently, I'm supposed to choose the main beam members as 'Haunched' members rather than 'prismatic' members. This enables one to use the steel member option as a brace.
I also discovered that the option to design of the Apex haunch seems to only be for the American codes. How can I switch to the design with the British codes?
Thanks
