Beam-column joint details

[Subject Prev][Subject Next][Thread Prev][Thread Next]
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 thoughts?  Any references to justify your approach?
