Multi-Storey Office Design: Comparative Analysis of RC and Structural Steel Schemes with Basement Addition

This solution provides a comparative design analysis between a Reinforced Concrete (RC) scheme and a structural steel frame with composite metal deck slabs for a multi-storey office. Key structural features include achieving column-free space at Level 1 using Vierendeel girders and trusses, alongside the use of cellular beams and curved RHS perimeter beams.

The design addresses critical city-centre constraints, including noise/vibration limits, restricted access, and height restrictions. It also covers basement excavation implications, such as secant piled walls and dewatering. Detailed calculations include wind and snow loading, truss member sizing, column buckling, deflection checks, and raft foundation bearing capacity. Deliverables include schematic sections, plan views, load run-downs, a construction method statement, and a project programme.
