Punching shear, chord plastification, and branch member buckling checks under CIDECT Design Guide 3 and Eurocode 3 Part 1-8 for tubular lattice joints.

Double-Truss Tubular Nodes: Welded Intersecting Branch Connections & Dynamic Wind Fatigue Resistance

1. Chord Plastification Checks for Tubular Truss Connections

Direct welded tube-to-tube lattice trusses eliminate bulky gusset plates, reducing overall building self-weight. Champion verifies chord face yielding and branch member punching shear against Eurocode 3 (EN 1993-1-8) design limits.
