Multi-Storey Mixed-Use Steel Frame with Plate Girders, Braced Stability, and Piled Foundations

This solution details a six-storey mixed-use steel frame featuring a combination of primary beams and deep plate girders for load transfer. The design addresses critical site constraints, including poor soil bearing capacity and a high groundwater table, necessitating a piled foundation system.

Technical calculations include plate girder design (bending, shear, and deflection), lateral stability analysis under wind loads using CHS bracing, column capacity checks, and end-bearing pile design according to Eurocodes. Deliverables comprise schematic floor plans, pile cap details, a technical letter regarding secant piled walls for a basement car park, and a comprehensive construction method statement with a project schedule.
