HEA 500 beams framing into an HEB 600 column

HEA 500 beams framing into an HEB 600 column

HEA 500 beams on both sides of an HEB 600 column, bolted through end plates with stiffeners in the column. A lightly loaded joint: the welds reach 29 % of capacity.

Overall check: plastic strain and component status.

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.
