A Consecutive Missing-Data Recovery Method for Bridge Health Monitoring Based on an ICEEMDAN-PE-LSTM-Informer Hybrid Model

Accurately reconstructing consecutive missing measurement segments presents a major challenge in bridge structural health monitoring, due to the inherent complexity and non-stationary nature of the collected signals. To address this, a hybrid data recovery framework is developed...

Freezing performance of selective artificial ground freezing based on three-pipe structure and its influencing analysis

Selective artificial ground freezing (S-AGF) enables directional cooling and mitigates unnecessary thermal loss through air-insulated casings, thereby exhibiting superior energy-saving and stratum-protection performance relative to conventional artificial ground freezing (C-AGF)....

Coupled Effects of Filler Aspect Ratio and Interfacial Characteristics on the Mechanical/Thermal/Electrical Properties of Graphene Nanocomposites

ABSTRACT Owing to interfacial defects and filler‐size effects, mechanical/thermal/electrical experimental performances of graphene‐reinforced polymer nanocomposites frequently deviate greatly from theoretical predictions. This study develops a cross‐scale multi‐physics effective...

An identification and classification framework for bridge cracks using transposed convolution-CBAM-Segformer with transfer learning

Bridge cracks seriously affect structural bearing capacity, durability and traffic safety, making accurate and efficient crack detection essential for bridge maintenance. To address the problems of feature degradation and upsampling information loss in existing segmentation model...

Evaluating the impact of mainline slope on temperature distribution in a branched tunnel fire: An experimental study and theoretical model analysis

Smoke and heat transport in branched tunnel fires become more complex when an inclined mainline is subjected to longitudinal ventilation. This study conducted 1:20 reduced-scale experiments to investigate the maximum ceiling temperature rise and temperature longitudinal decay in...
