Multi-Storey Steel Frame with Diagrid Exoskeleton and Deep Bored Piles

This solution compares a structural steel frame featuring a diagrid exoskeleton and composite metal decking against a reinforced concrete scheme utilizing Vierendeel girders and ground-level arches. It addresses city centre site constraints, restricted structural zones, and poor soil bearing capacity.

Technical content includes Eurocode-based wind and snow loading, total vertical load run-down, and detailed design of braced bays using Macalloy bars. It features comprehensive checks for beam vibration, column buckling, and deep bored pile foundations considering skin friction and group action. Deliverables include schematic plans, connection details (full penetration welds), a construction method statement, and a project programme.
