By Which method,RCDC calculate K factor of column ? For Sway or Non -sway frame alignment chart or else ?
It follows annex-E of IS:456-2000 code. It is based on stability index calculation.
When a column in one direction has beam while the other direction does not have beam,do rcdc detect that automatically and select the appropriate effectiv3 length for design?
yes.. You can also use some limits or fixed value if required. See help file for details.
Thank you
In RCDC, while the column is in sway condition, k is usually shown as 5 . But If i check k manually with the help of an alignment chart of sway frame, then I find less than 5 .
