Comparative Design of Steel Truss and Precast RC Sway Frame Structures over Live Railway Lines

This solution provides a comparative analysis of two structural schemes for a building spanning a railway: a structural steel truss system with composite metal decking and a precast RC sway frame utilizing hollowcore planks and a cable-stayed roof.

Key engineering challenges addressed include working over live railway lines, managing tight site constraints, and ensuring Class 2B robustness. Detailed design tasks include 30m steel truss analysis, RC beam and column capacity checks, tie design for lateral stability, and bored pile foundation design in stiff clay.

Calculations cover wind loading, deflection (SLS), and ULS requirements referencing Eurocodes. Deliverables include general arrangement drawings, connection details, foundation details, a construction method statement, and a project programme.
