Comparative Analysis of RC Frame and Steel Frame Schemes featuring Vierendeel Girders, Composite Slabs, and Piled Foundations

This solution provides a comparative analysis of two structural schemes: an RC frame with precast ribbed slabs and a raft foundation, versus a steel frame utilizing Vierendeel girders, composite metal decks, and contiguous piled walls.

Key engineering challenges addressed include basement excavation constraints, lateral stability via diaphragm action and braced bays, and the structural implications of light well removal. Detailed design checks include wind loading, deflection limits, and member sizing for primary/secondary beams, columns, and piles.

Deliverables include comprehensive load run-downs, schematic plan and section drawings, a detailed construction method statement (covering top-down construction), and a project programme.
