Taidi System Technical Whitepaper: Post-Tensioned Wide Flat Beam Solution for Covered Underground Garage Roofs
Covered underground garage roofs face combined loads from soil cover, fire truck loads, and groundwater uplift. Flat slabs risk punching shear, while conventional beam-slab systems increase floor height. The Taidi system uses post-tensioned wide flat beams to save approximately 500 mm in floor height and excavation depth compared to beam-slab systems, and eliminates punching shear risks versus flat slabs. This whitepaper details technical principles, comparisons, and applicable conditions for commercial developers and structural designers.

This article examines the risks associated with underground garage roof slabs, particularly flat plate systems, and presents the post-tensioned wide beam and slab solution (Taidi) as a safer and more economical alternative. It outlines key considerations for project owners and designers during the conceptual phase.

Flat slabs are widely used in standard underground garages, but for roof slabs with soil cover, the additional loads from soil weight, fire truck loading, and landscape surcharge significantly increase punching shear at column heads, raising the risk of sudden failure. This article explains the structural limitations of flat slabs in such scenarios and introduces the Taidi prestressed wide-shallow beam system, which eliminates punching shear risk while saving approximately 500 mm in floor height.
