I Just created a structure in staad in which there are no errors. I have done analysis. But after imported it to Rcdc but in which some columns are missing i don't know why i checked it's properties, supports etc.
Blue Marks are missing columns & in 2nd image that is how it is coming in Rcdc
Hi,
RCDC detects columns at all the levels and the Levels from a STAAD model are detected from the Y coordinate of each node present in the STAAD model.
Coming to column, the Column is identified ranging between 2 levels depending upon its start and end node.
So in your case, considering example of column C5 --- you will be able to see the column C5 at all those level where the member breaks. Like on the levels 0.009m, 1.529m, 2.739m, 5.636m, 9.293m, 12.342m & 15.391m you will be able to see column C5 as it is broken at the level with presence of a node where as at other levels like 0.011m or 1.979m you wont be able to see column C5 as it is not broken there or in short there is no node at that particular level.
For column C5, as per the model...RCDC will identify the column as mentioned below.
Hope this clarifies. Kindly revert for more clarification if required.
Thanks.
