In alternate load‑path narratives for disproportionate‑collapse avoidance, why is horizontal tie continuity highlighted beyond merely upsizing seismic factors?

Choices

  • (A) Random column splices suffice
  • (B) Catenary and arching redistribution needs collector ties bridging removed supports
  • (C) Deflection polishing alone rewires shear paths
  • (D) Delete all nonstructural cladding references

Correct answer: (B)

Catenary and arching redistribution needs collector ties bridging removed supports

Explanation

Robust diaphragm ties enable catenary paths after localized column loss.
