Control of Subduction Zone Age and Size on Flat Slab Subduction

open access: yesFrontiers in Earth Science, 2020
Flat slab subduction is an enigmatic style of subduction where the slab attains a horizontal orientation for up to several hundred kilometers below the base of the overriding plate.

Constraining Mantle Viscosity Structure From a Statistical Analysis of Slab Stagnation Events

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The viscosity structure of Earth's mantle, even the 1‐D radial viscosity profile, remains not well constrained. The dynamics of the subducting slabs is strongly affected by, and can be used to constrain, the viscosity structure of the mantle.

Punching Shear Characterization of Steel Fiber-Reinforced Concrete Flat Slabs

open access: yesHighTech and Innovation Journal, 2022
Punching shear failure in thin slabs under concentrated loads can cause shear stresses near columns. The use of steel fiber is a practical way to improve a slab-column connection's punching strength and deformation capacity.

Influence of cratonic lithosphere on the formation and evolution of flat slabs : insights from 3-D time-dependent modeling. [PDF]

open access: yes, 2015
Several mechanisms have been suggested for the formation of flat slabs including buoyant features on the subducting plate, trenchward motion and thermal or cratonic structure of the overriding plate.

Structural Behaviour of Voided Flat Slab With Various Void Ratios Under Vertical Loading

open access: yesCivil and Environmental Engineering, 2023
In recent modern buildings, voided slabs have been implemented because of the high reduction of their weight up to 35 %. Also, CO2 emission takes place which was developed from mass concrete.
