Xinrongmao Cold Chain Project

Upon project completion, the post-tensioned wide shallow beam solution met backfill load safety requirements while providing the structural space needed for the AS/RS. Rack installation proceeded smoothly without conflicts between structure and rack layout. Compared to conventional frame beam-slab structures, floor-to-floor height was reduced by approximately 500 mm, lowering excavation and backfill costs. Compared to flat slabs, structural safety was enhanced, passing engineering review and alleviating the owner's safety concerns. This project demonstrates BICP's '3D BIM collaborative analysis and design of building and rack systems at the planning and design stage' in a high-end intelligent cold storage facility, validating the applicability of the post-tensioned wide shallow beam solution under complex loading conditions (backfill + heavy AS/RS). The project provides a reference for cold storage facilities converted from underground garage roofs with heavy backfill, where flat slab punching shear limits are exceeded and high headroom is required, as well as for intelligent cold storage projects needing precise AS/RS adaptation.
