Grade Beam Construction Joints
Grade Beam Construction Joints
(OP)
Anyone know of a code mandated construction joint distance? I have a typical wall construction joint distnace not to exceed, and now the question has come up - "what about the grade beams, then?".

In the past, I have specified a limit of 400 cy of concrete in one day's placement - but haven't done that for a while as I think it invades the means and methods of the contractor.
In terms of controlling cracks, etc., I wouldn't think it necessary to use CJ's at all unless the grade beam is some kind of wall system where large areas of concrete were exposed to view. In that case, I'd probably specify vertical formed goove joints near midspan.

The larger amount of longitundinal steel, the farther apart the spacing of the joints can be. The steel helps reduce the cracking. Since a grade beam typically has more longitundinal steel than a wall, the spacing between joints can be further apart than walls.
