Having selected trial groups for column design I have found that the output optimises the column the bottom storey but then only uses that trial group for the rest of the column line
e.g. I have trial groups of UC254x254, 305x305UC and UC356x406 as per the ramuk.col file
At Storey 1, the only section that works is in UC356x406., but at upper storeys the column selected is still from UC356x406 (235kg/m) when a UC254x254x89kg/m section would also work.
Is there a setting to change this to select from the lightest trial group at every storey?
or is the solution to use a single customised trial group containing all the sections I wish to consider
