Large-Span Covered Market with Pitched Steel Trusses and Driven Pile Foundations

This solution presents a structural steel design for a large-span covered market featuring 60m pitched roof trusses and 20m secondary trusses. It addresses key challenges including a 200m+ building length requiring movement joints, a 10m cantilever overhang, and poor soil conditions managed via driven precast piles.

Technical content includes wind loading calculations per Eurocodes, member sizing for SHS trusses and UC columns, and serviceability deflection checks. The paper compares a steel scheme against an RC frame alternative. Deliverables include a detailed method statement, construction sequence, general arrangement drawings, and a professional letter analyzing the structural implications of converting the roof to a public access area.
