RE: Chords in concrete and masonry buildings

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The steel angle ledger is never "continuous".  For fabrication/erection
the angles will probably be made in 20 ft lengths.  "If" you can to
count on this for your chord, you need to detail splices at the
discontinuities.

Subject: Chords in concrete and masonry buildings


When designing a concrete or masonry shearwall building with flexible
roof
or floor diaphragm, does the chord have to be taken by continuous bars
in
the concrete or masonry that are placed at the elevation of your
diaphragm,
even if you have steel ledgers that are continuous at the perimeter of
the
diaphragm.  Could the steel ledger be used as a chord? or is this
against
the code.  

TIA
