Punching strength of reinforced concrete flat slabs without shear reinforcement
Revista IBRACON de Estruturas e MateriaisPunching strength is a critical point in the design of flat slabs and due to the lack of a theoretical method capable of explaining this phenomenon, empirical formulations presented by codes of practice are still the most used method to check the bearing

International Journal of Applied Mechanics and Engineering, 2023 From among the several types of slabs, there is uncertainty about the most cost-effective one for structures with short, medium, and long spans. A study comparing the cost of the solid, flat, hollow block (HB), and post-tensioned (PT) slabs for 4, 6, and

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