effective cmu lintel depth for o.o.p. loads
i can't find any guidelines on how much cmu lintel depth you are allowed to consider for out of plane loads. specifically, a wind load from a large window below. this will end up as a line load load at the bottom of the lintel. it doesn't seem like i'd be allowed to use, say 6 foot of depth to resist that concentrated line load.
check out our whitepaper library.
this link might help,
you normally should be able to consider all the reinforced lintel as resisting such load from wind. in any case you can apply such load to the reinforced lintel and see how it affects the behaviour.
rather large curtain wall, ceruvious? can you put some kickers from your lintel up to the floor or roof framing, or would they protrude into the architects ceiling?
