Design of Moment-Resisting Column Base Plates - Structville
Forces in T-stubs of the base plate Assuming that tension is resisted on the line of the bolts and that compression is resisted concentrically under the flange in compression, the lever arms from the column centre can be calculated as follows: z t = 380/2 = 190 mm z c = (276.3 – 25.3)/2 = 125.5 mm

STRUCTURE magazine | Base Plate Design for Post-Installed ...
Base plate design" is a frequently misunderstood term, particularly when discussing attachments for post-installed anchoring applications. This article explains how the concept of base plate design, which is typically understood in the context of "column base plate design," is not necessarily relevant to fixture attachment for post-installed anchoring applications.

On Vertical Mills, the 4th Axis is frequently parallel to X or Y, and is laid down. On a Horizontal Mill, the 4th Axis is also parallel to X or Y, but it is standing up. Both methods work great, but the horizontal mill's standing 4th axis frequently has more clearance available since the work is never trapped between the table and the axis.

base plate when the anchor bolts are loaded in tension. Different behaviour should be considered when strength, stiffness and rotational capacity of the base plate loaded by bending moment have to be predicted, see [1]. The column base stiffness is in particular influenced by behaviour of the tension part of the base plate, see [2].
