Can a flexible diaphragm be horizontally cantilevered?
Situation: Steel framed building with several bays; interior bays are braced
but it is desired to avoid bracing in the end bays. Diaphragm is a metal
deck and is considered to be flexible. Normally lateral loads on a flexible
diaphragm are distributed by tributary area to support elements - but how
would distribution be handled for horizontally cantilevered end diaphragms?
