How can we change the Un-supported length in RCDC when column is tied in one direction and is free in another direction?
Considering below example when there is a case where a column is not tied along one direction and is tied along another direction, the unsupported length of the column along the direction where it is not tied is to be manually entered in RCDC using the 'Redesign Section' tool available in RCDC.
With this option, the actual unsupported length = (Floor height - the Beam depth) needs to be manually entered in RCDC.
Once this height is entered; the column section is redesigned and the redesigned data is accepted, the revised height of the column at selected floor will be displayed in the design calculation report as well.
Below are the snips for reference;
