concrete moment frame - beam/column connection
concrete moment frame - beam/column connection
(OP)
Hey all - I am working on a large analysis project. There are about 15 different buildings (already constructed or under construction) and all of them use the same concrete moment frame as the main LFRS. The original drawings do not have a lot of detail so the construction details were in question.
We just recently found out that the column reinforcing does not hook into the continuous beams. It extends up into the beams but does not hook.
It's my understanding that whatever moment is in the beam at the support needs to be transferred into the column by way of the reinforcing -- can the transfer occur if the r/f is not hooked?
Thanks

If the beams were designed based upon fixity and moment transfer into the columns, then the bars must be developed. But with As(req'd) / As(provided) applied, the 18 inches might be enough.

Also, if the columns continue to the floor above, then the moment can be transferred via concrete compression struts from the columns above and below.
