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

Deep 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

Masonry Wall Performance Estimation Under Blast Loading: A Study Using Finite Element Analysis

Mekanika
This paper studies the dynamic response of masonry wall structures under blast loading. It requires a detailed understanding of the explosion phenomenon, wave propagation, and the structure's response to these shocks.

Empirical Coastal Atmospheric Corrosion of Masonry Metal Wall Ties

Corrosion and Materials Degradation, 2021
Not counting domestic dwellings, it has been estimated that in Australia alone, some tens of thousands of masonry buildings and structures have exceeded their design life, with many of these being at risk of partial (or worse) collapse from falling or ...

Study on the Influence of Slope Static Load on Shallow Lining Support Structure

Energy Science &Engineering, EarlyView.
On the basis of the background of the shallow‐buried main adit supported by stone lining, the mechanical model of the supporting structure is constructed, and the stability of the supporting structure is analyzed by using the methods of field investigation, theoretical analysis, and numerical simulation.

High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste

Polymer International, EarlyView.
Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments

Developing a seismic retrofitting solution for wall-to-floor connections of URM buildings with wood diaphragms [PDF]

, 2014
Out-of-plane collapse of masonry walls in unreinforced masonry (URM) buildings has been identified as a major local failure mechanism affecting the global stability of a structure. Continuity between structural elements maintains proper load paths during
