Overview
Tall building design is dominated by lateral loads — wind and seismic forces that dwarf gravity at height. This skill covers structural systems, wind engineering, vertical transportation, and fire-evacuation strategy for skyscrapers.
When to Use
- Designing buildings over 150m tall
- Selecting lateral-load-resisting systems
- Planning elevator zoning and sky lobbies
- Developing fire-evacuation and refuge-floor strategies
Key Principles
- Lateral system — core + outrigger, diagrid, tube, or mega-frame; choice depends on height and form.
- Wind engineering — wind tunnel testing required above 200m; facade pressure drives cladding design.
- Elevator zoning — local + express banks; sky lobby at 1/3 and 2/3 height for supertall.
- Refuge floors — every 15-25 floors in supertall; pressurized, fire-rated.
- Damping — tuned mass dampers or liquid dampers reduce wind-induced sway.
Process
- Define height, floor plate, and occupancy.
- Select lateral-load system based on height-to-width ratio.
- Commission wind tunnel study.
- Design vertical transportation — elevator banks, sky lobbies, fireman's lifts.
- Plan fire-evacuation strategy with refuge floors.
- Detail facade for wind pressure and thermal movement.
Common Pitfalls
- Ignoring wind-induced motion — occupants feel acceleration above 15 milli-g.
- Undersized elevator system — long wait times kill building appeal.
- No refuge floors — supertall fire evacuation takes hours without them.
- Flat facade in wind zone — suction forces can exceed positive pressure.
