Steel Portal Frame Manufacturing Building with Overhead Crane, Transfer Girders, and Foundation Comparison

This solution details the design of a steel portal frame manufacturing building incorporating a 3-story office and storage block. The structural concept focuses on achieving a column-free showroom using heavy transfer plate girders and integrating an overhead crane system with runway beams and surge girders for lateral stability.

Key engineering challenges addressed include crane-induced surge loads, strict deflection limits (L/600), and foundation selection based on soil profiles. Technical calculations cover preliminary member sizing (UKB), plate girder web buckling, and a comparative analysis between pad footings and CFA piles. Deliverables include detailed load paths, schematic elevations, and a professional scheme selection matrix.
