How flat slabs at subduction zones are created remains unclear. Here, the authors show that the Nazca slab has retreated at ∼2 cm per year since 50 Ma but no rollback has occurred in the last ∼12 Myr in the flat slab, implying that an overpressured sub ...

Load-defl ection behaviour of hybrid concrete flat slab
Due to the important role of high strength concrete in the structural systems, present work focuses on the use of this material as a strengthening technique incorporating with the normal strength concrete in flat slab system.

Light Collimation and Focussing by a Thin Flat Metallic Slab [PDF]
We present experimental and theoretical work showing that a flat metallic slab can collimate and focus light impinging on the slab from a punctual source. The effect is optimised when the radiation is around the bulk, not at the surface, plasma frequency.

Shear wave velocities in the Pampean flat-slab region from Rayleigh wave tomography: Implications for slab and upper mantle hydration [PDF]
The Pampean flat-slab region, located in central Argentina and Chile between 29° and 34°S, is considered a modern analog for Laramide flat-slab subduction within western North America.

Finite element implementation of punching shear behaviors in shear-reinforced flat slabs
Punching shear reinforcement systems such as studs and stirrups are used to improve the punching shear strength of flat slabs. A three dimensional finite element model (FEM) is developed through Ansys 10 computer software, to carry out the nonlinear ...

Comparison of punching shear requirements in BS 8110, EC2 and MC2010 [PDF]
This paper compares design provisions for punching shear at internal columns in the superseded British Standard BS 8110, Eurocode 2 (EC2) and fib Model Code 2010 (MC2010).

Proposed structural system for mixed hollow flat slab
The economic design of the slabs is the most influential on the construction cost and choosing the appropriate system is the key to the slabs optimal design, and there are many systems that have been developed recently to reach the most economical design.

Geometry and seismic properties of the subducting Cocos plate in central Mexico [PDF]
The geometry and properties of the interface of the Cocos plate beneath central Mexico are determined from the receiver functions (RFs) utilizing data from the Meso America Subduction Experiment (MASE).

S‐Wave Receiver Function Analysis of the Pampean Flat‐Slab Region: Evidence for a Torn Slab
Flat‐slab subduction is an atypical form of subduction where the downgoing plate assumes a low‐angle or subhorizontal geometry as it descends beneath the overriding plate.

Shear and Flexural Behavior of Flat Slabs Casted with Polyolefin Fiber-Reinforced Concrete
This paper presents the influence of polyolefin fiber on the flexural and shear attitude on the flat slabs. Three slab sets (80 cm × 80 cm) were tested, each with a thickness of 10 cm.
