Dimensional Behavior of Nail-Laminated Timber-Concrete Composite Caused by Changes in Ambient Air, and Correlation among Temperature, Relative Humidity, and Strain

open access: yesBioResources, 2023
A timber-concrete composite (TCC) slab composed of nail-laminated timber (NLT) and topping concrete (TC) was developed for flooring applications. The NLT was laminated alternately with lumber and plywood.

Improved construction of concrete viaducts with movable scaffolding systems in Spain [PDF]

open access: yes, 2016
The current paper relates the state of the art of construction of viaducts with a movable scaffolding system (MSS). Two different procedures are introduced: the traditional sequence and the new sequence applied to some viaducts in Spain.

Atlas of the underworld : Slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity

open access: yes, 2017
Across the entire mantle we interpret 94 positive seismic wave-speed anomalies as subducted lithosphere and associate these slabs with their geological record.

Thermo-physical Properties and Mechanical Properties of Burn-resistant Titanium Alloy Ti40

open access: yesJournal of Aeronautical Materials, 2017
As a functional material of burn-resistant titanium alloy, the physical properties of Ti40 alloy were first reported. The chemical compositions of Ti40 alloy ingots by VAR were uniform. The microstructures of Ti40 alloy slab manufactured by HEFF+WPF were

Comparative Study Of Conventional Slab, Flat Slab And Grid Slab Using ETABS

open access: yesIOP Conference Series: Materials Science and Engineering, 2021
Abstract In today’s construction, the traditional slab is mostly supported by a beam, with a small slab thickness and a large beam depth, and the weight is carried from beam to column. The flat slab allows architects to place partition walls wherever they are needed. It is widely used because it reduces weight, speeds up building, and is

Formation of Fluctuations in the Molecular Slab via Isobaric Thermal Instability [PDF]

open access: yes, 2007
The frictional heating by ion-neutral drift is calculated and its effect on isobaric thermal instability is carried out. Ambipolar drift heating of one-dimensional self-gravitating magnetized molecular slab is used under the assumptions of quasi ...

Effect of concrete strength and thickness of flat slab on preventing of progressive collapse caused by elimination of an internal column [PDF]

open access: yesJournal of Structural and Construction Engineering, 2019
Designing structures against progressive collapse is an important part of the building design. However, some guidelines such as GSA and UFC holds implications for reducing the risk of progressive collapse of structures, but because the nature of the ...

Juan de Fuca subduction zone from a mixture of tomography and waveform modeling [PDF]

open access: yes, 2012
Seismic tomography images of the upper mantle structures beneath the Pacific Northwestern United States display a maze of high-velocity anomalies, many of which produce distorted waveforms evident in the USArray observations indicative of the Juan de ...

Aging and distributional tone learning: the role of pitch memory in older adults’ discrimination of mandarin lexical tones

open access: yesLanguage and Cognition
Distributional learning enables listeners to form phonetic categories by extracting statistical regularities from speech input. Younger Cantonese speakers can acquire the Mandarin level-falling (T1–T4) contrast through distributional learning, with ...
