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

Research on Damage Characteristics of Brick Masonry under Explosion Load

Shock and Vibration, 2021
As the main structural component of partition wall or load-bearing wall, brick masonry has been widely used in construction engineering. However, brick and mortar are all brittle materials prone to crack.

Finalisation of the European Approach to Assess the Fire Performance of Facades—Brief Information on the Outcome of the Project

Fire and Materials, EarlyView.
ABSTRACT This research was conducted within the framework of project SI2.825082, funded by the European Commission—DG GROW. The project's objective was to finalise a European approach for assessing the fire performance of façades under medium and large fire exposure conditions.

Quasi-Static Testing of Unreinforced Masonry Walls Using Different Styles of Basalt Fiber Mortar Surface Reinforcements

Buildings
To investigate the reinforcement effects of different reinforcement methods including basalt fibers on unreinforced masonry walls (UMWs), this study examined three reinforcement methods: ordinary mortar, basalt fiber mortar, and basalt fiber mesh mortar.

Factors determining the quality of masonry – differentiation of resistance and reliability

Budownictwo i Architektura, 2020
A house or any other building without walls is truly hard to imagine. The first thing usually associated with walls is, of course, masonry. Today, masonry walls perform a load-bearing function in buildings up to four above-ground floors, in the higher ...

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

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.

Numerical Simulation of Unreinforced Masonry Buildings with Timber Diaphragms

Buildings, 2021
Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the effect of the connections between floors and walls is rarely discussed or explicitly modelled when simulating the response of such buildings.

Achieving Sustainable Development Goals Through Social Life Cycle Assessment: A Case Study of Portuguese Forest Wood Supply Chains

Sustainable Development, EarlyView.
ABSTRACT Social considerations are often overlooked in efforts to achieve sustainable development, despite being critical for building equitable and resilient global value chains. This study addresses this gap by applying a social life cycle assessment to three key Portuguese forest wood supply chains—uncoated woodfree paper, natural cork stoppers, and

Study on the Seismic Performance of Autoclaved Fly Ash Brick Masonry Walls Restrained by Assembly Ring Beam and Construction Column

工程科学与技术, 2018
In order to solve the brick masonry structures’ problems such as the low level of earthquake fortification, non-standard construction and energy-wasting features of wall materials in masonry structures, a new-type assembly autoclaved fly ash brick ...
