Large-Span Glulam Tied Arch & Steel Pratt Truss Leisure Facility with Cantilever RC Pool Walls

This solution compares two structural schemes for a leisure facility: a large-span (30m) glulam tied arch system with braced bays and a structural steel curved Pratt truss system. It includes masonry blockwork, hollowcore composite floors, and cantilevered RC pool walls.

Key challenges addressed include lateral stability for large spans, managing groundwater/uplift, and designing for no external columns. Detailed calculations cover glulam arch thrust and buckling, steel truss member sizing, column axial/bending checks, RC pad and strip footings, and cantilevered pool wall soil retention.

Includes design appraisals, carbon footprinting (A1-A3), client communications, method statements, and comprehensive GA drawings (roof, foundation, and elevation details).
