Airport Control Tower Design: Steel Truss Superstructure with Braced Bay Stability and Piled Raft Foundation

This solution compares a structural steel scheme and a reinforced concrete scheme for an airport control tower. The recommended steel design utilizes a roof truss, primary and secondary beams with a metal deck slab, and a braced bay system for lateral stability.

Key challenges addressed include wind loading at height, Class 3 importance requirements, and foundation design on sandstone. Technical calculations cover wind pressure, member capacity checks (SHS, UC, UB), Macalloy tie design, and raft foundation bearing capacity using Eurocodes (BS EN 1990-1997).

Deliverables include schematic plans, structural sections, and a formal client letter discussing the implications of increasing tower diameter and height.
