PCI Connection Details
PCI Connection Details
(OP)
Hi,
The PCI connections manual shows a detail for connecting a precast column to a footing using a socket which the column sits in and is grouted. No shear connectors or bars which extend out of the concrete.
I am in a seismic area and while I don't have any net direct tension in my columns I'm a bit concerned but not having a positive connection.
I've been searching the PCI design manual and ACI for recommendations on minimum connection requirements but haven't found anything.
The contractor certainly prefers this connection detail compared to bolting or welding the column to the footing via embeded plates.
Am I being too cautious here? Any thoughts
Thanks

The advantage though of the socket type detail is the higher moment capacity at the base on the connection.
The structure in question sits on these columns and has no shear walls and in essence will function as a cantilever column system.
Are you in a seismic area?
