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

BioResources, 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.

Subduction Duration and Slab Dip

Geochemistry Geophysics Geosystems, 2020
The dip angles of slabs are among the clearest characteristics of subduction zones, but the factors that control them remain obscure. Here, slab dip angles and subduction parameters, including subduction duration, the nature of the overriding plate, slab

Two-way patched RC slabs under concentrated loads [PDF]

Инженерно-строительный журнал, 2020
Damage that occurs in reinforced concrete elements can reduce the capacity and serviceability of these elements. One of the damages that may be encountered is spalling or delamination of concrete covers.

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

Journal 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 ...

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

Language 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 ...

Review of seismic velocity anomalies in the lower mantle

地球与行星物理论评, 2023
The lower mantle accounts for more than 50% of the total volume of the Earth, and influences the evolution of the Earth. Early studies showed that the lower mantle is relatively homogeneous, but since the 1970s, seismic tomography revealed the velocity ...

Philippine Sea and East Asian plate tectonics since 52 Ma constrained by new subducted slab reconstruction methods

, 2016
We reconstructed Philippine Sea and East Asian plate tectonics since 52 Ma from 28 slabs mapped in 3‐D from global tomography, with a subducted area of ~25% of present‐day global oceanic lithosphere.
