Describe the column and beam sections, the design forces at the joint, the end plate geometry with its four overhangs, the bolt grid, and the weld throats. Mia builds a small RFEM 6 model, runs the Steel Joints add-on, and reports the governing utilisation across plates, bolts, and welds.

Worked example
HEB 200 · IPE 300 · NEd 50 kN + VEd 80 kN + MEd 60 kNm

- Beam-to-column joint

Design a bolted extended end plate connection between an IPE 300 beam (S235) and a HEB 200 column (S235) with NEd = 50 kN, VEd = 80 kN, MEd = 60 kNm at the joint. End plate 15 mm S235 with a 60 mm top overhang, flush elsewhere, 4 rows x 2 columns of M20 grade 8.8 bolts at 90/140 mm spacing and 45 mm edge distance, 8 mm flange welds and 6 mm web welds, EN-recommended values.
Calculate the example with MiaKey results
- Governing utilisation
- η = 0.81 (bolts)
- Plate utilisation
- η = 0.66
- Weld utilisation
- η = 0.54
All values are deterministic for the stated inputs. Design forces applied exactly at the joint via a short cantilever stub; EN-recommended partial factors.
- — Column web and flange are unstiffened.
- — Bolt grid is treated as a uniform rectangular pattern (equal row and column spacing).
Required inputs
- Column and beam cross-sections and steel grades
- Design forces NEd, VEd, MEd at the joint
- End plate thickness, grade, and the four overhangs
- Bolt grid (rows x columns, spacing, edge distance), diameter, and grade
- Flange and web weld throat thickness
- National Annex
What you receive
- Governing check and utilisation
- Plate utilisation (bending/tension components)
- Bolt utilisation (tension, shear, bearing, or combined)
- Weld utilisation (flange and web)
- Assumptions and normative references

What this skill checks
Unrestricted rectangular bolt grid
Configures any rows-by-columns bolt pattern with row/column spacing and edge distance, not limited to a fixed catalogue layout.
Four-sided plate overhang
Sets the end plate overhang beyond the beam profile independently on all four sides (top, bottom, left, right).
Definable weld throats
Sets the flange and web fillet weld throat thickness independently and reports their utilisation.
Component-by-component utilisation
Runs the RFEM 6 Steel Joints add-on (EN 1993-1-8 component method) and reports the governing utilisation for plates, bolts, and welds.

Frequently asked questions
Frequently asked questions
Do I need an existing RFEM model?
No. Mia builds a small column-and-beam model from the sections you give it and applies your design forces directly at the joint.
Can I set a different overhang on each side of the plate?
Yes. Top, bottom, left, and right overhang are independent inputs.
Is the bolt grid limited to a standard layout?
No. Any number of rows and columns is supported, with your own spacing and edge distance.
What determines the governing check?
Mia runs the RFEM 6 Steel Joints add-on (EN 1993-1-8 component method) and reports the highest utilisation across the plate, bolt, and weld checks.
