Dear Sir

This is a special type of structure. there are all inclined column present in the structure. RCDC trying to identify at least one vertical column in analysis file.

in this case as there are no single vertical column present in structure, it is showing error of column missing.

I have created a updated STAAD file with one dummy vertical column. RCDC will read this file and you can proceed with the design. Updated STAAD file is attached file for your working.8712.Structure2_Updated.STD
