|That is, to be
able to support the greatest amount of load on a column provide lateral

“lateral bracing at intervals equal to or less than the critical length” may
or may not result in an efficient tower.
can save structure weight by omitting a bracing level if you don’t need the
full strength of the column – this is an arrangement that you can experiment
with. You will do this when you try to
optimize (make as efficient as possible) your design.

sure that both columns fail at the same time – the connection of the
horizontal member to the column is usually not adequate enough to provide
