In seismic design, when defining Newmark combinations for combining seismic loads i x and y direction, how can I include these in my code combinations instead of the simple load cases for x and y direction only? May they only be combined manually with other load cases? Does load groups and relations have anything to do with it.
In my test file (attached), the combinations seem to be correct, but the combination table still displays only the newmark combinations, while in the drop down menu for selecting cases/combinations, they are all present. Any reason for this?
Thanks in advance!
