Impact of Cold Storage Structural Scheme Selection on Operations: A Full-Cost Comparative Framework

Structural scheme choice also drives 20-year operating costs: storage capacity, refrigeration energy and joint maintenance. This article establishes a full-cost comparative analysis framework between large-span post-tensioned and traditional small-span schemes for a reference 20,000 m², 8-story cold storage, illustrating operational economic implications from three dimensions: storage utilization, floor height savings, and reduced expansion joints. Suitable for owners planning new cold storage facilities. (Note: Figures are reference examples; actual projects should be calculated with specific parameters.)
