Thanks all for the replies.
I think when the members are shorter, design coefficient should be lower. but now it is larger. do you know what is the reason?
(I want to compare the results with RSTAB software so I forced to break the elements)
I'm using SAP2000 in order to design a structure. I want to compare SAP results with another software so that I should divide lines (members). But design ratios changed a lot when I divide them and I don't understand what is the reason...
