Comparative Design of RC Vierendeel Frame and Steel Frame with Cantilevered Floors & Pile Foundations

This solution provides a comparative analysis of two structural schemes for a multi-storey building: a Reinforced Concrete (RC) option utilizing Vierendeel girder action and cellular beams, and a structural steel option featuring metal deck slabs and diagonal struts for cantilevered floors.

Key engineering challenges addressed include lateral stability via sway frames and braced bays, diaphragm action, and basement construction using secant piled walls. Detailed design checks cover wind loading, slab/beam/column sizing, retaining wall stability, and foundation design (raft vs. under-reamed bored piles).

Deliverables include schematic plans, section details, connection details, and a professional client letter addressing the structural implications of landscaping additions. All designs reference Eurocode standards.
