Large-Span Sports Arena with Tensioned Cable Roof, Concrete Frame, and Piled Foundations

This solution details the design of a large-span sports arena featuring a lightweight roof system comprising a concrete compression ring and radial tensioned steel suspenders connected to a central hub. The structural scheme includes a reinforced concrete frame with columns, deep beams, and shear walls acting as diaphragm elements for lateral stability.

Key engineering tasks include wind loading analysis, suspender elongation and deflection checks, ring beam axial and moment capacity, and column buckling. Foundation design addresses varying ground conditions using piled foundations. The solution also includes a professional client letter evaluating the structural implications of adding a heavy advertising box, alongside a construction method statement and programme.
