Preventing Underground Garage Roof Collapses: The Post-Tensioned Wide Beam and Slab Solution
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.

Industrial floors are typically cut with joints every few meters as an industry practice. However, joints are not irreplaceable—they are a compromise solution to concrete shrinkage, leaving long-term issues such as spalling, hygiene contamination, and AGV interference. This article explains the origin and limitations of joints from the mechanism of concrete shrinkage, and then illustrates how post-tensioned integrated floor systems actively suppress cracking by applying pre-compression, extending joint spacing from ≤6 m to the order of 150 m.

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.

Over the past three decades, prestressed technology in China has evolved through three phases: introduction (1990s, learning international standards), accumulation (2000s, localized application and standard co-development), and innovation (2010s to present, scenario-specific breakthroughs). Now entering a new stage of digitalization and internationalization, this article traces the trajectory and highlights BICP's contributions—3D finite element optimization algorithms, BICP-ST cryogenic anchorage system, and participation in eight industry standards.

In post-tensioned structures, the quality of corrugated metal ducts is often overlooked yet critical. Insufficient wall thickness can lead to damage during construction, poor grouting, and corrosion pathways, all invisible after concrete placement. This article explains the role of metal ducts, the hazard chain of inadequate thickness, key inspection points, and the quality control approach of Shente-Taimao ducts.
