This might be a discussed question in this forum but I really have problem understanding the effective length so please forgive me for asking 
I am confused by how to define translation restraint for columns. Does this restraint need to be directly on column ends or can I rely beams that connects to column to bring translation restraint from far ends.
I have uploaded a pic together with a screenshot of standard regarding effective length. My question is how much the effective length in X direction is gonna be for the column in red? As I have bracing at void ends, can I reply beams B1 to bring the translation restraint in X direction from bracing for column in red so the effective length of column will be 3 meter or do I need to take a full length which is 9*2.2(sway) meters as the effective length in X direction?
What if I introduce a transfer beam to terminate the column as shown in section A-A option 2? How much is the effective length is gonna be for that red column in X direction then? Thank you.
