Multi-Storey Hotel & Conference Facility: Steel and RC Schemes with Central Core Stability & Piled Foundations

Solution Overview

This solution evaluates two structural schemes for a multi-storey hotel and conference facility: a structural steel frame with a central stability core and an RC frame utilizing Vierendeel girders and waffle slabs. It addresses critical challenges including fully glazed elevations, lateral stability, and poor soil conditions requiring bored piles to rock level.

Technical content includes ULS load run-downs, wind loading calculations, and member design for trusses (UC/SHS) and columns. It features detailed checks for deflection (L/500) and the design of a secant piled retaining wall with anchors. Deliverables include general notes, typical floor plans, and detailed sections of the foundation and structural connections based on Eurocodes.
