Base plate design example.

Ok base plate required thickness. In this case the base plate may be designed as follows. N d 2 3 in b bf 2 3 in 2. The bolts are cast into the concrete base in location tubes or cones and are fitted with anchor plates to prevent pull out.

Typical column bases as shown below consist of a single plate fillet welded to the end of the column and attached to the foundation with four holding down bolts.

I divide the factored column load by the design bearing strength of concrete and find the area of the base plate.

A w10 x 49 column is supported by a concrete pier whose top surface is 19 inches x 19 inches.
