Lakeside Multi-Storey Building: Reinforced Concrete and Structural Steel Frame Schemes with Cantilevered Elements & Pile Foundations

This solution presents two structural schemes for a multi-storey lakeside building: a Reinforced Concrete (RC) frame and a Structural Steel frame. The RC scheme utilizes shear walls, backspan beams, and raft or strip foundations on compacted fill. The steel scheme features metal deck slabs, inclined roof trusses, and comprehensive bracing systems to ensure diaphragm action.

Key challenges addressed include cantilevered external spaces, lakeside construction constraints (flooding and water-side methodology), and foundation design in silty sandy gravel and dense sand. The solution includes soil profile analysis, SBC calculations, and detailed schematic drawings for plan layouts, sections (A-A, B-B), and roof bracing configurations.
