Shrinkage in Conc and Supporting Precast
Shrinkage in Conc and Supporting Precast
(OP)
I have a project where I need to add some CIP beams below some existing double tees. The beams will support a vehicle loading traveling across the DT's. I estimate the height of the CIP beam will shrink between 1/64" and 1/32". What are people opinions/concerns regarding this gap and possible impact from the vehicle load closing this gap again and again over time?
I have no reasonable way to preload the system to remove this potential shrinkage gap. thanks

Michael.
Timing has a lot to do with the outcome of a rain dance.

Hokie66, I understand what you mean. The new loading is only applied directly over the new CIP beams, the DT stem acts like a short column. As far as the DT knows its span hasn't changed as there is virtually no Live Load other then the vehicle. The DT is already there and supports the DL. I will not be getting negative moments, or substantially reduced positive moments in the DT
