Haunched IPE 400 beam on an HEA 340 column with a tubular brace
An IPE 400 beam with a welded haunch is bolted to an HEA 340 column, and a tubular brace lands on the same node. M20 and M24 bolts; plates 10–20 mm.

How it was checked
Every plate, bolt and weld in one model
The joint is modelled with shell elements for the plates and member ends, and with nonlinear springs for bolts, welds and anchors (the component-based finite element method). The member forces are applied at the member ends and the model is loaded step by step to the full design load.
Plates pass when the plastic strain stays below the limit of the code; bolts, welds and anchors are checked against the component resistances of AISC 360-16. The bars above show each component’s utilisation for the governing load case.
