Multi-Storey Building with Post-Tensioned Transfer Beams, Shear Walls, and Pile Foundations

This solution compares a steel sway frame with an RC scheme featuring precast post-tensioned (PT) transfer beams to accommodate a large yacht exhibit void. The RC design utilizes flat slabs, hollowcore roof planks, and corner shear walls for lateral stability of the glass-clad structure.

Key engineering challenges include managing large spans, ensuring robustness (Class 2B), and designing foundations for stiff clay and rock. Detailed calculations cover wind loading, PT beam balancing and stress checks, column buckling analysis, and pile capacity. Design is performed in accordance with Eurocodes (BS EN 1990-1997). Deliverables include schematic plans, sections, bending moment diagrams, and reinforcement detailing for slabs and columns.
