Investigating flat-slab subduction underneath South America using 4D numerical simulations
… provides an opportunity to study mechanisms of flat-slab subduction and the nature of mantle seismic structures. Subduction occurring at this location is characterized by along-trench variation from flat- to steep-dipping slabs, as indicated by both seismic images and geological observations. …

Punching shear capacity of flat slab-column junctions (a study by 3-D non-linear finite element analysis)
… presents a study of punching shear capacity of flat slab-column junctions. A three dimensional non-linear finite element program based on 20 node isoparametric solid element was used for the investigation. The non-linear 3-D elastic isotropic model proposed by Motsovos was used to describe the …

Experimental and Theoretical Investigations of a New Flat Slab System Incorporating GFRP Stay-In-Place Structural Forms and Embedded I-Beams
A novel steel-free concrete flat-slab design for floors is introduced. It includes embedded glass fiber-reinforced polymer (GFRP) I-sections as primary and secondary beams, with columns supporting the primary beams. GFRP stay-in-place (SIP) structural forms span the spacing between, and are bonded …

Distribution and Rates of Quaternary Deformation within the Pampean Flat Slab Segment of the Central Andes of Argentina from 30-32°S
The Pampean Flat Slab is characterized by a wide zone of active upper-plate deformation that involves both thin- and thick-skinned deformation. It provides a rare opportunity to explore the possible control of slab geometry, deformation style, and tectonic evolution of structures on upper-plate …

Autoclaved Aerated Concrete Tile Vaults for Lightweight Floor Systems
… of multistory buildings, the reinforced concrete flat slab is a preferred floor system in part due to ease of formwork construction, which does not require skilled labor. However, the flat slab carries load primarily in bending, forcing much of the concrete section to crack because of the low …

Punching failure and compressive membrane action in reinforced concrete slabs
… membrane action in reinforced concrete slabs provides a basis for the development of a more realistic design approach for continuous slabs subjected to concentrated loadings.The results of an extensive series of tests on one quarter scale models of the interior slab—column connection in …

Analytical and numerical studies of heat and moisture transfer through porous insulation
… developed for heat and water vapor transfer in flat-slab and round-pipe thermal insulations. The model is validated by comparing its predictions with available experimental data. The effective thermal conductivity of the insulation in the presence of condensation depends on seven design and …

A House For A River Rat
… Its foundation is of a concrete two way flat slab supported by concrete caissons, its walls are of reinforced concrete masonry units, and its floors and ceilings are of small timber frame construction.

Seismic retrofitting of deficient Canadian buildings
… loading, such as unreinforced masonry buildings, flat slab concrete buildings and steel frame buildings. It then presents the most common retrofitting strategies applicable to low-rise buildings commonly found in major Canadian cities. A case study assessing the performance of hybrid base …

The behaviour of modern flexible framed structures undergoing differential settlement
… open plan buildings with a frame consisting of flat RC slabs, RC columns and non-load bearing internal and external partitions and facades. These modern framed structures are more flexible than older conventional buildings with load bearing walls and are less susceptible to differential …

Standoff screws functioning as mechanical shear connectors in composite joists
… base angle thickness, screw embedment depth, slab thickness, and slab width. The objectives of the testing were (1) to provide an understanding of the strength of the standoff screw in various test geometries and (2) to provide an understanding of the slip characteristics, or ductility, of the …

Vaulted Earthen Floor Systems for Low-Cost Housing Construction
… floor systems consist of a reinforced concrete flat slab, which is problematic as concrete and steel are expensive, carbon-intensive materials. As urbanization rates increase globally, informal and structurally inadequate settlements become more ubiquitous as a result. Vaulted structural floor …

Evaluating the Controls of Neogene Exhumation in the Tropical Northern Andes (colombia)
… Andes has responded to Neogene variations in slab geometry, climate, and drainage reorganization. I also discuss how the Neogene topographic changes may be one of the drivers that make the tropical Northern Andes of Colombia one the world's most biodiverse places on earth. I used a geomorphic …

The real strength of laterally restrained reinforced concrete slabs
… enhancement exhibited by laterally restrained slab system . This strength enhancement is in excess of that estimated by standard flexural and shear design methods.<br/><br/>Although of the fact that the consideration of CMA in design can lead to substantially reduced quantities of flexural …

A Geophysical Survey Of Active Volcanism In The Central And Southern Andes
… between 33°S and 46°S are separated by a zone of flat slab subduction and differ significantly in the manifestation of current volcanic activity. The CVZ has been considered less hazardous due to the few number of historical volcanic eruptions compared to the SVZ, yet it contains the largest …

Tectonic-Climate Interactions And Glacial History Within The Chugach And Kenai Mountains, Alaska
… Peninsula, underlain by the transition from flat slab to normal subduction. The region is characterized by old AHe ages which mimic the subduction angle of the down going plate and decrease away from an exhumational hotspot at a syntax in the Chugach Mountains. We attribute the long term …

Stratigraphic response to Cordilleran processes along the south central Andean margin
… and chronostratigraphic record of Neogene Andean flat-slab subduction. Coeval cycles of upward coarsening stratigraphic trends, erosional unroofing, deformation, and magmatic high flux events provides new evidence of upper-plate Cordilleran feedbacks driven by changes in subduction regime. This …
