Comparative Design of Monolithic RC Frame vs. Pin-Jointed Steel Frame with Large Transfer Spans

This solution provides a comparative structural design for a multi-storey facility, evaluating a monolithic RC frame against a pin-jointed steel frame. Key features include managing 24m transfer spans using RC slabs or steel trusses and addressing complex ground conditions near a lake, including liquefaction risks and sand layers.

Engineering analysis covers foundation selection (driven piles vs. shallow pad footings with vibro-compaction), lateral stability via RC shear walls or steel cross-bracing, and diaphragm action. Design checks include slab thickness, transfer beam depths, and waterproofing requirements (BS 8001). Deliverables include schematic elevations, split plans, functional load path diagrams, and a comprehensive scheme comparison matrix covering buildability, fire protection, and material efficiency.
