CN Tower: 553 m Free-Standing Concrete Telecommunications Tower
Y-shaped tapered hollow concrete shaft, SkyPod observation sphere, Space Deck, and 106 m steel broadcast antenna.
Verify lateral wind sway, second-order P-Delta moments, and modal frequency spectra of the 553 m tower under extreme Lake Ontario wind gusts, preventing fatigue failure of the upper antenna mast.
1. Geometry & FEA Mesh
- •Tapered Y-shaped concrete shaft from ground z = 0 to 335 m: base footprint radius R = 33 m tapering smoothly to R = 12 m
- •Central hollow hexagonal/circular core with internal diaphragm rings every 25 m
- •7-storey cantilevered donut-shaped SkyPod observation complex (Ø 36 m) supported on radial structural outrigger brackets
- •Space Deck observation level at z = 447 m
- •106 m multi-stage tubular steel broadcast antenna mast tapering from Ø 1.8 m to Ø 0.6 m at the summit (z = 447 to 553 m)
2. Loads & Boundary Conditions
- •Fixed 6-DOF boundary supports across foundation footprint at z = 0
- •Self-weight gravity with heavy mass concrete and mechanical plant loads
- •Lake Ontario boundary-layer wind force along +X scaling up to 553 m
3. Simulation Results & Findings
- ✓Lateral drift at SkyPod and summit stays well within structural serviceability criteria
- ✓Modal analysis cleanly separates the lower tower cantilever sway from the high-frequency antenna mast modes
- ✓High critical buckling multiplier confirms exceptional safety factor of the tapered Y-shaft
