Case Studies in Construction MaterialsReinforcement corrosion weakens the punching shear capacity of RC flat slabs. This study tested twelve large-scale slabs (1500 × 1500 × 100 mm) with hooked-end steel or macro-synthetic fibers (0.5–1.0 % by volume) and control samples.

Analysis of instability of tall buildings with prestressed and waffle slabs
Revista IBRACON de Estruturas e MateriaisThe construction system of prestressed flat slabs has been gaining market in Brazil, since it eliminates the use of beams, allows you to perform structures under coluns by area and reduces the cycle of concrete slabs.

Structural robustness of concrete flat slab structures
, 2017 Current building regulations for design against progressive collapse normally use prescriptive rules and risk based qualitative scales which are insufficient to cover current needs in design. Structural robustness of concrete flat slab structures is examined using different theoretical models to capture the dynamic behavior under accidental events.

Punching strength of flat slabs with and without shear reinforcement
Građevinar, 2015 The punching shear strength is an extremely significant parameter for the design of flat slabs, i.e. the slabs supported directly on columns, without beams between columns.

Numerical Modeling of Post-Tensioned Concrete Flat Slabs with Unbonded Tendons in Fire
Engineering ProceedingsThe structural fire of post-tensioned concrete flat slabs with unbonded tendons has not been well investigated so far. An investigation based on experimental results was conducted in this study using a numerical model.

A comprehensive bibliometric analysis of punching shear failures in flat slabs
Discover Civil EngineeringFlat slabs face significant structural challenges because of punching shear failure. The mechanism by which flat slabs fail through punching shear has received considerable attention through experimental and computational research but needs a thorough ...

Slab underthrusting is the primary control on flat-slab size
Science AdvancesFlat subduction, an intermittent phenomenon along active margins, arises from well-known causes, yet the mechanisms driving its expansion remain poorly understood. The prevailing view suggests that trenchward continental motion drives slab overthrusting, causing the flat slab to expand oceanward.

Spherical void formers in concrete slabs
Journal of the South African Institution of Civil Engineers, 2010 Large span concrete flat-slab systems with internal spherical void formers (SVF) have been used in Europe for over a decade. They are bi-axially reinforced concrete flat-slab systems with a grid of internal spherical void formers.
