RE: Yet another Wind question

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I don't think the trigger exists with respect to MWFRS. I have some
older posts about this here and on eng-tips. A structural element or
system is MWFRS depending on its function in the structure, not on its
size. The tributary area of 700sf is not a part of the definition of
MWFRS but is a helpful exception that allows C&C elements with TA larger
than 700sf to be treated as MWFRS. As you say, if the intent is there
then the rules should be revised.

Josh, Scott,

Thanks very much for the responses.  I hadn't noticed the 700sf trigger 
before.  If all of us are correct in our reading of this, it isn't a 
major problem.  But I gotta say if this is the intent of the code 
writers (which seems incredible), it sure is an screwy way to 
implement it.

MJ
