Column Base Plate Calculator
Steel column base plate on a concrete foundation — EN 1993-1-8 component method with EN 1992-4 anchor design. Enter the column, plate, anchors and axial/moment/shear loads for a live plan and elevation, the concrete bearing-pressure and anchor-tension distribution, the effective bearing area, joint resistances, full design checks and a printable step-by-step calc sheet.
Runs the validated STATIX base-plate engine (incl. InFaSo & IDEA base-plate examples)

Base plate
Design code
Single-code module — column base plate component method (EN 1993-1-8) with EN 1992-4 anchor design. Anchor type & concrete state below switch the EN 1992-4 clauses.

c1 is the distance from the anchors to a free edge of the concrete, which is not the anchor inset on the plate above: a 400 mm plate with anchors 60 mm in can still sit in the middle of a large slab. Declare an edge and EN 1992-4 §7.2.2.4 concrete edge breakout and §7.2.2.5 pry-out are checked; leave it as none and they are reported as not applicable rather than passed.

Step-by-step calculation
Connection take-off — all base plates
Every base plate in the project, aggregated into a connection take-off — plate, anchors and weld per element with estimated steel mass. Use “Add base plate” above to build the schedule, then Download PDF (print → Save as PDF). Masses are nominal for take-off only.
This isn't a toy calculator
It runs the same engine as STATIX — a full structural suite built on the same engine. Model the whole building and its connections, not just one base plate.
