Precast Columns on a steel baseplate

[JStructsteel]

Doing some precast columns (not part of lateral system) and they will be on steel baseplates. Would you match the anchorage of the baseplate and develop with the steel in the column, or just provide anchorage for construction loads and shear required?

You did not mention if the base plate is larger than column or not..

The following excerpt from PRECAST CONCRETE HANDBOOK ..

I cannot give you the formula for success, but I can give you the formula for failure..It is: Try to please everybody.

You need to consider structural integrity.

These baseplates are outside the columns. The columns are not cantilevered

JohnRwals, what type of load would be used? If my column had 10-#6 bars, what would be a good anchorage for the integrity? 5? 3? all 10?

You can check PCI Design Handbook, "Column Connection-Base Plate and Anchor Bolt Design."
