Multi-Storey Building Design: RC Core & Flat Slab vs. Steel Frame with Piled Foundations

This solution compares two structural schemes for a six-storey building: a reinforced concrete (RC) frame featuring a central stability core and flat slabs, and a structural steel frame utilizing metal decking and a rigid moment-resisting frame.

Key engineering challenges addressed include the prohibition of support from an existing tower, tight site boundaries, and poor ground conditions requiring bored piles to rock. Technical calculations include Eurocode-based wind loading, RC shear wall design, flat slab punching shear, beam ULS/deflection, and column buckling checks.

Deliverables include detailed schematic plans, sections, foundation layouts, and a professional client letter addressing the structural implications of adding an atrium opening.
