Comparison of Braced Steel Frame and RC Moment Frame with Truss Roof & Piled Raft Foundation

This solution evaluates two structural schemes: a braced steel frame with hollow-core slabs and a reinforced concrete moment frame. The design features a roof-level truss to support corner columns and cantilevered beams.

Key challenges addressed include lateral stability under wind and torsional loads, and managing settlement via a piled raft foundation on sandy gravel. Engineering checks include Eurocode-compliant loading, column buckling, truss member sizing, and serviceability deflection limits for slabs and ties.

Calculations cover wind pressure, micro pile capacity, and tie rod sizing. Deliverables include schematic floor plans, elevations, connection details, and moment distribution diagrams.
