Enhancing the Seismic Resilience of Masonry‐Infilled RC Structures Using Rubber Joints: Full‐Scale 3D Shaking Table Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Masonry infills in reinforced concrete (RC) frames are highly vulnerable to seismic damage, often sustaining severe cracking even under moderate ground motion, which in turn leads to considerable economic losses and safety risks. To address this issue, this study experimentally evaluates the effectiveness of two innovative rubber‐based joints ...

Damage Characteristics and Stress Distribution Law of Overburden Rock in Multiple Mining of Close Coal Seams

Energy Science &Engineering, EarlyView.
This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Numerical analysis of AAC block masonry wall with CFRP & GFRP laminates under blast loading

Discover Applied Sciences
Vehicle-borne and person-borne improvised explosive devices (IEDs) have become increasingly frequent in recent malicious attacks. Generally, Trinitrotoluene (TNT) is used in all explosive devices, targeting key building components to cause structural ...

Whole‐House Thermal Bridge Modelling for Accurate Retrofit Energy Prediction

Energy Science &Engineering, EarlyView.
This study models thermal bridging in a UK semi‐detached house across pre‐ and post‐retrofit scenarios using piecemeal and whole‐house approaches with EWI and IWI. Whole‐house retrofits reduce heat transfer coefficient by 60%; findings demonstrate that default values are often unrepresentative and advocate tailored Ψ value databases.

Simplified Design of Masonry Ring-Beams Reinforced by Flax Fibers for Existing Buildings Retrofitting

Buildings, 2020
Seismic events have repeatedly highlighted the vulnerability of existing masonry buildings. Seismic retrofitting is frequently focused on improving the connection between walls and roof for ensuring behavior able to resist loads from any horizontal ...

Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

Fire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

Non-Linear Seismic Analysis of Masonry Buildings [PDF]

, 2010
Non-linear analysis is the most viable tool to get accurate predictions of the actual response of masonry structures under earthquake loading. Analytical methods based on the idealisation of masonry walls with openings as systems of macro-elements allow ...

Numerical modeling of reinforced masonry walls under lateral loading at the component level response as opposed to system level response

Ain Shams Engineering Journal, 2019
Many experimental and analytical investigations were carried out on fully-grouted reinforced masonry shear walls types (rectangular, flanged or end-confined) to investigate their behavior under lateral loads.

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
