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?
A validation of the same can be found in the below link.
