25 composite action
25% composite action
i remember reading somewhere that composite beams require at least 25% composite action in order to qualify as composite.
is this listed in any code specification, and if so, could someone please direct me to it?
thanks
check out our whitepaper library.
it is not actually a code requirement, but 25% is the typically accepted minimum for a number of reasons. see the commentary to i3 the 2005 spec (13th ed. manual) - p16.1-311 item 3.
