The bolts are cast into the concrete base in location tubes or cones and are fitted with anchor plates to prevent pull out.
Circular column base plate design example.
I design base plates for circular columns using the aisc asd manual pages 3 106 to 3 110.
To calculate c i use the formula for m since the formula for n does not apply.

M u t b x a 5 6 kn m effective plate width.
The forces and deformations from the structural analyses used to design the column base plate connection are dependent on the choice of the column base plate connection details.
Of the column base plate connection in the elastic and plastic ranges and for seismic loading possibly even the cyclic force deformation relations.
Base plate required thickness.
The forces and deformations from the structural analyses used to design the column base plate connection are dependent on the choice of the column base plate connection details.
Also it seems to me that the formula for n will not apply unless the column is very large in diameter allowing the portion of the base plate inside the column to.
Note the aisc design guide 1 base plate design procedure for wf columns if used for hss columns would assume a bending plane at the face of the hss column and the portion of the plate beyond the column as a cantilever.
Of the column base plate connection in the elastic and plastic ranges and for seismic loading possibly even the cyclic force deformation relations.

Problem statement it is required to specify the appropriate thickness of a base plate to support a uc 203 x 203 x 60 subjected to.
Design of column base plates 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.
2 plate that represents a steel structure 2 plate is mainly used as a connection piece or as a floor plate.
The dimension between the anchor bolt and the bending plane is the moment arm to be used in solving for the base plate thickness.
