Bolted T-stub in tension
Feasibility prototype — not for design use. The calculation has not been validated for design decisions.
The T-stub is the basic component of bolted end plates, column flanges and base plates in tension. Enter the geometry, steel grade and bolts: the drawing and the EN 1993-1-8 design check update as you type. The finite-element verification runs in this browser — the input stays on your device.
Checked
- EN 1993-1-8 Table 6.2 modes 1–3 with prying, for an equal-leg T-stub with one bolt row on each side of the web
- Web in tension (6.2.6.8), bolt punching (Table 3.4), spacing and edge distances (Table 3.3)
- FE shell model with plasticity, contact and bolt springs, as a cross-check at γ = 1
Not checked
- The effective length: enter L = leff of the governing yield-line pattern yourself
- Welds and the root fillet (enter the EN m), bolt shear and bearing, preload, bolt bending
- Bolt rows acting as a group, backing plates, the connected members

Detailing and checks
Assumptions
FE verification (in this browser)
Shell model of flange and web with plasticity, contact on a rigid support and bolt springs, loaded step by step to 5 % plastic strain or bolt yield. It uses characteristic strengths (γ = 1) and is compared with the EN component model at γ = 1 — a check of the component model, not a design value.
Drag to rotate. Bolt forces in kN at the resistance event (red: bolt at 0.9 fub As).
