A Newly Discovered Late‐Cretaceous East Asian Flat Slab Explains Its Unique Lithospheric Structure and Tectonics

Journal of Geophysical Research: Solid Earth, 2021
The existence of historical flat slabs remains debated. We evaluate past subduction since 200 Ma using global models with data assimilation. By reproducing major Mesozoic slabs whose dip angles satisfy geological constraints, the model suggests a ...

Geodynamic models of short-lived, long-lived and periodic flat slab subduction

Geophysical Journal International, 2021
Flat slab subduction has been ascribed to a variety of causes, including subduction of buoyant ridges/plateaus and forced trench retreat. The former, however, has irregular spatial correlations with flat slabs, while the latter has required external ...

Prestressed Concrete Flat Slabs

1977
A short review on the analysis and the design of prestressed flat slabs is given. Some new aspects concerning flexural behavior, punching, reinforcement arrangement and detailing are presented. Different possible tendon layouts are compared. A new model for slabs with unbonded tendons and additional reinforcement is described.

Design of slab–column junctions in flat slabs

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2003
In a flat-slab type construction the most vulnerable areas from the point of view of safety of the structure are the junctions between the slabs and the columns. As architects and engineers strive to achieve increasingly slender forms of construction the vulnerability of the slabs to punching increases.

Slab Rollback Versus Delamination: Contrasting Fates of Flat‐Slab Subduction and Implications for South China Evolution in the Mesozoic

Journal of Geophysical Research: Solid Earth, 2020
Growing evidence supports that the widely developed Mesozoic folds and magmatism in the South China Block are attributed to the flat‐slab subduction, followed by slab steepening, of the Paleo‐Pacific Plate (PPP).

Neogene Retroarc Foreland Basin Evolution, Sediment Provenance, and Magmatism in Response to Flat Slab Subduction, Western Argentina

Tectonics, 2020
Understanding the effects of flat slab subduction on mountain building, arc magmatism, and basin evolution is fundamental to convergent‐margin tectonics, with implications for potential feedbacks among geodynamic, magmatic, and surface processes.

Moments in Flat Slabs

Journal of the Structural Division, 1956
Results of study of moments in cast aluminum model of flat slab floor; all panels were square, and columns and capitals were round; model was two bays by three bays and was tested under air pressure with pattern type loading; moments obtained from SR-4 strain gage readings are compared with those obtained by continuous frame analysis following American
