Anatomy in Brief

  • Tri-pod base morphs to circular shaft aloft.
  • Central shimbashira-style core for seismic resilience.
  • Diagrid lattice for stiffness with less steel.

2011 works

Quick Glossary

  • Shimbashira: central pillar concept adapted from pagodas.
  • Diagrid: diagonal grid structure that carries load efficiently.
  • TMD: tuned mass damping to reduce sway.

Construction Notes

  • Off-site fabrication minimized on-street disruption.
  • Wind-tunnel tests refined the tower profile.
  • Maintenance catwalks baked into the lattice.
Why so tall?
