Numerical research on anti‐dislocation measures design of deep‐buried tunnels in an anisotropic rock mass area

Deep Underground Science and Engineering, EarlyView.
This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

Bio‐based tannin‐loaded layered double hydroxides in epoxy coatings for smart corrosion protection of steel in underground infrastructure

Deep Underground Science and Engineering, EarlyView.
This study presents a sustainable smart‐coating strategy for protecting underground steel infrastructures from chloride‐induced corrosion. Zinc‐aluminum layered double hydroxides (LDHs) and tannin‐loaded LDHs (LDH–TA) were incorporated into an epoxy matrix to provide both enhanced barrier properties and active, pH‐responsive inhibition.

3D Printed Concrete: Fresh and Hardened Properties

Periodica Polytechnica Civil Engineering
3D concrete printing (3D CP) is an advanced form of additive manufacturing (AM), that allows for the creation of complex geometrical structures using concrete. This technology has the potential to reduce construction time and labour costs while minimizing material waste.

Valence Asymmetries of Traits in Dating Contexts

European Journal of Social Psychology, EarlyView.
ABSTRACT Research on traits in dating contexts has typically focused on trait content. We instead examined structural differences in trait frequency and similarity. Prior work suggests that positive information is more frequent, whereas negative information is more diverse and less similar.

Mechanical characteristics and structural performance of rubberized concrete: Experimental and analytical analysis

Case Studies in Construction Materials
Rubberized concrete is referred to as ''green concrete'' by replacing fine aggregate with used tire rubber. However, although significantly increasing ductility, rubber particles lowered compressive strength.

The gut microbiome and drug‐resistant epilepsy: Microbiome–antiseizure medication interactions and implications for pharmacoresistance

Epilepsia Open, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects approximately one‐third of patients with epilepsy and represents a major unmet clinical need. While traditional hypotheses of pharmacoresistance have focused on alterations in drug targets, efflux transporter overexpression, and intrinsic disease severity, the gut microbiome has recently emerged as a ...

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Influence of the Boundary Conditions on the Seismic Response of Existing Masonry Infills From In‐Plane and Dynamic Out‐of‐Plane Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...
