Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

CFD supported modelling of double skin facades in hot arid climates [PDF]

open access: yes, 2005
Previous simulations predict the possibility of reducing cooling demands in office buildings in hot arid areas if a selective double skin facade is used.

Out-of-Plane Response of Infill Masonry Walls [PDF]

open access: yesThe Open Construction and Building Technology Journal, 2012
The in-plane effect of infill walls on the structural response of reinforced concrete frames has been widely acknowledged via numerous experimental and numerical investigations and, as a result, the need to consider their effect on structural response has been acknowledged (indicated) in the latest generation of structural design codes worldwide.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Seismic Behavior of Bahareque Walls Under In-Plane Horizontal Loads

open access: yesBuildings
This study investigates the structural behavior of bahareque earth walls, a traditional construction system commonly used in rural areas of northern South America. Bahareque (wattle and daub) walls, consisting of guadua (a bamboo-like material) or wooden

Sustainable Live Sound Monitoring and Classification System Enabled by a Triboelectric Nanogenerator and Machine Learning Techniques

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A high‐performance Triboelectric Nanogenerator (TENG) acoustic sensor using polyimine/graphite polypropylene (PI/GP) was developed for real‐time, sustainable sound monitoring and classification. The self‐powered device delivers 25.67 μW output power, 92.7% accuracy with MobileNet V1, and powers a wireless transmission circuit, demonstrating dual ...

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Influence of infill on the cyclic behaviour of traditional half-timbered walls [PDF]

open access: yes, 2013
Half-timbered buildings represent an important historical heritage in many countries. They are diffused in various regions for different reasons, such as availability of materials, to lighten a structure, low cost and the strength they offer, and as a ...

Horizontal stiffness of masonry walls infilled frame

open access: yesMATEC Web of Conferences
Walls used to fill a frame structure may serve non-load bearing (visual, acoustic or fire separation) or load bearing and stiffening functions which provide geometrical stability of a structure. They are shear walls without any vertical load from higher floors.

Nonlinear Response‐History Analyses of Masonry and Mixed Structures With HybriDFEM

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The hybrid discrete‐finite element (HybriDFEM) method, previously developed to perform static and modal analysis in discrete and coupled discrete‐finite element models, is extended to nonlinear response‐history analyses. The equations of motion for the HybriDFEM model are solved through various numerical time‐integration schemes, both explicit
