repair of dapped end of concrete purlin
i have a concrete purlin that bears on a column on its dapped end. the dapped end has excessive cracks and i'm looking for another way to transfer the loads to the column. "but clansman, put a bracket underneath and be done with it" .... not so fast. there's a pipe that runs down the column so a bracket will not work. i was thinking of supporting the purlin with hangars from the perpendicular girder, but those would have to extend out quite a bit to avoid the drain pipe, thought they would look a tad funny. anyone else have any ideas they can throw at me? see attachment so you can better grasp the last detail i mentioned. the picture does not show the connection with the pipe. thanks.

anyway to build a 'saddle' type bracket between the column and the purlin? (think of a simpson wood joist hanger for the general concept.)
