Chamfered joists mid50's

In a recent mud bed demolition, I came across roughly hand chamfered 2x8s as if with a hatchet. The joists were chamfered to 1/2" flat left on top. Spaces between joists were filled with 4" of concrete, level with
these chamfered joists then the mud bed. I am curious why the chamfer.

Might be hard to determine why unless it was needed to make the joists fit. Could be the joists were originally intended for something else but then used for that job. Pics might not tell us anything but they would be interesting to see - http://www.doityourself.com/forum/el...your-post.html

Hi Kirk,
Just a wild guess, since I have never see concrete filled between the joists, but perhaps the chamfer allows the concrete to be supported by the joists instead of just dead weight on whatever is below.
