Design uses the in-span value. Members with Δσ > 0 carry transverse load and reach their peak bending between the end nodes; reporting only end actions would under-report those members.
Test 3 — model diagnostics
PASS No singular stiffness matrix, all members have valid section properties and every joint is connected.
