Why can't I fix it

[serdagi]

Hello, there is a project that I am trying to make a steel observation deck. But for some reason I can't get the simplest element to be provided. Why does BE017 give an error in all types of sections? It provides 300 cuts like a joke. While it saves 200 sections even on the heaviest stair, why doesn't the CE076 strut be combined with a U profile, as in the "Joint Point" title I opened before?

Hello there; As I understand, you have just received the program, please attend this month's steel training. * Your r coefficients with high ductility level are 8 in your analysis settings. Such a simple non-multi-storey structure does not need to be solved with a high ductility level. The regulations allow you to use the ductility level as normal and the r coefficient as 4. Please review the regulations. Ductility level normally appears sufficient for all your sections. If you define a column with a U profile, enter the angle of the column as 90 and adjust the misalignment of the ladder beam. You need to ensure that the node is centered. The portions of the beam above the column are not trimmed. There is no problem in the formation of the merger. Good work.
