Post-fire structural behavior of reinforced concrete columns incorporating two types of waste glass: Experimental and numerical investigation on residual load-bearing capacity

This study investigates the axial compressive behavior and residual load-bearing capacity of concrete columns incorporating waste glass sand (GS) and waste glass powder (GP) after exposure to fire. Reinforced concrete short columns were prepared with GS as a partial replacement o...

Physics-guided CNN surrogate model of viscoelastic dampers and its application in structural seismic control

Accurate characterization of the time-domain nonlinear mechanical behavior of viscoelastic dampers (VEDs) remains challenging. Traditional frequency-domain models cannot simultaneously consider loading history, strain amplitude, and ambient temperature, whereas high-fidelity time...

Vibration model test and seismic performance evaluation of polypropylene fiber reinforced concrete lining of mountainside tunnels in Loess Plateau

Abstract Currently, tunnels are key infrastructure projects for traversing the Loess Plateau and ensuring rail connectivity. However, seismic damage surveys indicate that tunnels built along mountainsides in the Loess region suffer severe damage during earthquakes due to their lo...

National-scale hydroclimatic exposure screening of earthen heritage sites in China under changing precipitation regimes

Earthen heritage sites are highly sensitive to rainfall-induced erosion and moisture-related deterioration, yet their national-scale hydroclimatic exposure remains insufficiently quantified. Here, we compiled a geospatial database of 1,305 national-level earthen heritage sites in...

Integrating Ultrastable Cyclic Mechanoluminescence and Zero‐Thermal‐Quenching Photoluminescence Unlocks Multifunctional Optical Applications

ABSTRACT Excellent stability is essential for multi‐stimuli‐responsive luminescent materials toward high‐performance multifunctional optoelectronics. However, integrating cyclic‐stable mechanoluminescence (ML) and thermally stable photoluminescence (PL) into a single chemically s...

Synergistic Regulation of Homoacetogenesis and Electrochemical Electron Supply Enhances CO2-Assisted Caproate Production from Waste Activated Sludge

Abstract Municipal sewage treatment has become an energy-intensive sector associated with substantial CO2 emissions and waste activated sludge (WAS) generation. Chain elongation (CE), as a promising carbon resource recovery route, enables the conversion of sludge-derived short-ch...

Synergistic I 3 − Scavenging and Spontaneous Interphase Construction for Ultralong‐Life Zinc–Iodine Batteries

ABSTRACT Aqueous Zn–I 2 batteries combine safety, sustainability, and high theoretical capacity, making them a promising energy storage solution. However, their practical employment is impeded by challenges such as uncontrolled dendrite growth on the Zn anode, severe polyiodide s...

State of Health Estimation for Lithium-Ion Batteries in Energy Storage Systems: A Multi-Scale Spatiotemporal Deep Learning Approach

Accurate state of health (SOH) estimation of lithium-ion batteries is essential for ensuring the safe and efficient operation of electric transportation and grid-scale energy storage systems (ESS). However, extracting reliable degradation information from Battery Management Syste...

The indirect association between physical fitness and physical activity enjoyment through perceived sport competence among female university students: a cross-sectional study

Physical activity enjoyment is an important psychological correlate of sustained participation in physical activity. Female university students often report relatively low levels of physical activity participation and enjoyment, underscoring the need to identify factors associate...

Quality or convenience? Behavioral evidence on how facility grade influences urban destination choice

Modeling non-work activity destination choices is essential for urban transportation planning, as these activities involve greater flexibility and more complex behavioral decision-making than mandatory activities. However, existing studies often treat all facilities within the sa...

Research on accident risk prediction and grade classification of horizontal curve sections of expressways based on SHAP-SVR model

Conventional prediction models used in expressway risk-assessment systems often provide insufficient support for identifying and classifying crash-prone road segments. This study develops an interpretable framework integrating SHAP with support vector regression (SHAP–SVR) to pre...

Field investigation about thermal requirements area under local heating for rural house in Northwest China

Indoor heating zone could not be represented by architectural area. Precise heating control for the actual heat demand area is important for energy efficiency during heating period. Continuous whole-spatial heating will bring high energy consumption and serious energy waste as bu...

Methods for evaluating the seismic isolation performance of foam concrete shock-absorbing layers in mountain tunnels in high-seismic-intensity areas

Abstract Currently, a large number of post-earthquake surveys and statistical analyses of tunnel damage indicate that tunnels built against mountainsides are subject to the coupled effects of “asymmetric loads and seismic cyclic action,” which increase the risk of earthquake-indu...

Freeze–Thaw Durability and Pb Leaching Control of Graphene-Assisted MICP-Stabilized Pb-Contaminated Loess: Coupled Hydro-Environmental and Geotechnical Performance

Freeze–thaw cycling can strongly disturb the pore-water environment, soil fabric, and contaminant mobility of heavy-metal-contaminated loess, thereby threatening the long-term effectiveness of stabilization treatments in seasonally frozen regions. This study investigated the coup...
