Precast Tees - Topping Construction Joint Location?

[mrengineer]

When you have a construction joint in the topping over double tees (parallel to length of tees), what is the best location for the joint? (Center of tee, over tee stem, or at joint between tees?)

Logically it should be above the joint in the tees.


When things are steep, remember to stay level-headed.

Joint between tees.

Makes no difference structurally, but makes the resulting shrinkage crack straight.
