CHS 219.1 braces on an HEB 600 column
Two CHS 219.1 braces meet an HEB 600 column through bolted gusset plates. M24 bolts; local deformation of the tubes is checked as well.

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.
