Question: How do you
detail longitudinal beam and column rebar at a monolithic beam-column joint, at
than exterior column at roof level?
Addl info for
current consideration: Low-seismic region; two-story structure; rigid
concrete frame resists lateral loads; concrete roof beam frames into top of
exterior concrete column; typical beam details show top and bottom bars with
standard hooks extended into columns; and standard hooks are shown at tops of
longitudinal column bars.
Most references show
a detail at an intermediate floor level where the column is continuous above -
standard hooks at top and bottom beam bars are reasonable for that
configuration. But at the top of column, hooks at beam bars and at column
bars do not appear to provide sufficient continuity for moment transfer around
the outside face of the beam and column. Nevertheless,
drawings frequently show "typical beam details" for these columns
as well - and the design engineers argue that this meets the code.
Any references to justify your approach?
