Upper Concrete Decks Solve Wind Sway in Mass Timber High-Rise
Norway’s 85.4-meter Mjøstårnet demonstrates how mass timber scales to high-rise heights by resolving structural dynamics and fire safety through deliberate material trade-offs. By combining regional glulam frames with heavy concrete upper floors, the design tames wind-induced acceleration while maintaining rigorous passive burnout protection under European building standards.
