Andean flat slab subduction through time
(Geological Society of America, 2009)
The analysis of magmatic distribution, basin formation, tectonic evolution and structural styles of different segments of the Andes shows that most of the Andes have experienced a stage of flat subduction. Evidence is ...
Punching Strength of Flat Slabs with Unbraced Shear Reinforcement
(AMER CONCRETE INST, 2011)
This paper analyzes the punching strength of concrete flat slabs with shear reinforcement that does not embrace flexural reinforcement. This paper also reports the results of tests of slabs without shear reinforcement. ...
Upper mantle anisotropy beneath Peru from SKS splitting: constraints on flat slab dynamics and interaction with the Nazca Ridge
(Elsevier, 2015-02)
The Peruvian flat slab is by far the largest region of flat subduction in the world today, but aspects of its structure and dynamics remain poorly understood. In particular, questions remain over whether the relatively ...
Contribuição ao projeto e execução de lajes lisas nervuradas pré-fabricadas com vigotas treliçadas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECiv, 2010-02-18)
The big surge in use of systems for flat slabs gave up the search for freedom in the definition and organization of architectural interior spaces in buildings. The design and construction of buildings on flat slabs, which ...
Estabilidade em edifícios de concreto armado com pavimentos em lajes planas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECiv, 2007-08-24)
This present work covers possible manners of evaluating steel concrete frames designed for
multiple flooring buildings as far as instability and necessity of second order efforts are
concerned. Starting from single floor ...
Rock uplift at the transition from flat-slab to normal subduction: The Kenai Mountains, Southeast Alaska
(Elsevier, 2016-03)
The process of flat-slab subduction results in complex deformation of overlying forearcs, yet how this deformation decays with distance away from the zone of underthrusting is not well understood. In south central Alaska, ...
The role of ridges in the formation and longevity of flat slabs
(Nature Research, 2015-08)
Flat-slab subduction occurs when the descending plate becomes horizontal at some depth before resuming its descent into the mantle. It is often proposed as a mechanism for the uplifting of deep crustal rocks (‘thick-skinned’ ...
Thermo-mechanical analysis of the Andean lithosphere over the Chilean-Pampean flat-slab region
(Pergamon-Elsevier Science Ltd, 2017-09)
Flat subduction segments are generally related to cold lithospheric zones, which suggest low Heat flow values and therefore a deeper Curie isotherm. In this study we perform a geophysical analysis by using high - resolution ...
Seismicity and state of stress in the central and southern Peruvian flat slab
(Elsevier, 2016-05)
We have determined the Wadati–Benioff Zone seismicity and state of stress of the subducting Nazca slab beneath central and southern Peru using data from three recently deployed local seismic networks. Our relocated hypocenters ...
Neogene erosion of the Andean Cordillera in the flat-slab segment as indicated by petrography and whole-rock geochemistry from the Manantiales Foreland Basin (32°–32°30′S)
(Elsevier, 2015)
The Miocene Manantiales Foreland Basin is defined as a thick succession of sedimentary rocks belonging to the Chinches Formation in the Frontal Cordillera between 32 degrees S and 32 degrees 30 degrees S, located over the ...
