If there are secondary beams running between primary beams, and columns support the primary beams, then is it allowable to have the occasional secondary beam pinned to a column? Otherwise it seems to me that it would be impossible to connect a secondary beam to a primary beam at a location where a column is. For example, in the picture below, it appears as though the third secondary beam from the left is connected directly to the column. In this case, is the primary beam completely unaffected by this beam?
I was taught that if a beam is connected to a column then it is no longer a secondary beam. Moreover, would the analysis of a single primary beam not include the concentrated loads of the secondary beams which connect only to the column? And in practice, do structural engineers often do this?
