Abstract To utilize waste clay bricks and reduce carbon emissions, recycled brick powder (RBP) was prepared from waste brick-concrete structures and used to produce alkali-activated slag-recycled brick powder foam concrete (ASRFC). This paper evaluated the impact of RBP replacement rates and water-binder ratio on the physical and mechanical properties of foam concrete, including its thermal conductivity, strength, and pore structure. The results demonstrated that the addition of 10% RBP resulted in decreases in the apparent density and thermal conductivity of ASRFC, while flexural strength and the flexural-compressive strength ratio exhibited significant increases. These phenomena can all… More >

Abstract Interfacial adhesion failure is the primary limiting factor in the long-term durability of epoxy-emulsified asphalt micro-surfacing pavements. However, while digital image correlation (DIC) has been extensively applied to evaluate the bulk fatigue of traditional hot-mix asphalt and concrete, its specific application to the complex bi-material interface between rigid concrete substrates and cold-mixed, thermosetting epoxy-asphalt overlays remains limited. Consequently, current research lacks real-time data on full-field strain evolution and the transitional damage localisation mechanisms during dynamic fatigue processes under extreme temperature gradients. To this goal, three-point bending fatigue tests were performed at various temperatures (ranging from… More >

Abstract Buried natural gas pipelines are critical components of energy infrastructure, and their durability and safe operation depend on effective structural health monitoring and the early identification of damage states. In farmland environments, rotary tillage imposes repeated and often concealed mechanical loads on buried pipelines, resulting in stress accumulation, progressive deterioration, and potentially structural failure. However, predictive and interpretable health monitoring approaches that explicitly incorporate rotary tiller-induced damage mechanisms remain scarce. In this study, a physics-informed and interpretable hybrid framework is proposed for the structural health monitoring of buried pipelines subjected to rotary tiller loading. A… More >

Abstract Significant efforts have been made to increase the strength of concrete by using industrial waste such as fly ash and steel slag as partial substitutes for concrete in concrete. However, predicting the concrete’s compressive strength is a challenge as it is influenced by several factors such as the shape and size of the aggregate, the water-ratio balance. This study examines the predictive capability of three deep learning models: Bagging Extreme Gradient Boosted Model (BXGBM), Deep Random Vector Functional Link (DRVFL), and Kernel Extreme Learning Machine (KELM) on the prediction for compressive strength of concrete.

Abstract Temperature action is a primary environmental load that infrastructure endures during long-term service, and it is also one of the key causes of structural performance deterioration. With global warming and the increasing frequency of extreme weather, the temperature actions on structures are becoming increasingly complex and severe. Whether current design codes can adapt to environmental climate changes, particularly regarding how to effectively respond to the impact of extreme temperatures, has become a critical concern in engineering. Based on the current structural design codes of major countries and regions (including China, the United States, New Zealand,… More >

Abstract This paper introduces a novel external prestressing system specifically designed for strengthening hollow slab beams. To validate the system’s feasibility and isolate flexural behavior from interface slip effects, experimental investigations were conducted on monolithically cast specimens representing an idealized, fully bonded state. By integrating theoretical analysis, experimental testing, and finite-element numerical simulation, the study examines the mechanical behavior and design principles of the proposed configuration. Results indicate that the stress development process of the externally prestressed beam (N2) exhibits strong similarity to that of a conventional internally prestressed beam (N1).

Abstract This paper analyzes the influence of different fibers (polypropylene fibers and basalt fibers) and fiber contents (0%–0.20%) on the bonding performance between recycled coarse aggregate concrete and steel bars. The results show that the addition of recycled aggregates can reduce the fluidity of concrete, whereas the addition of fibers can further reduce the fluidity of concrete. The addition of fibers can effectively improve the mechanical properties of concrete (polypropylene fiber can increase compressive strength and splitting tensile strength by 7.80% and 6.09%, respectively, while basalt fiber can increase compressive strength and splitting tensile strength by… More >

Abstract Steel surface defect detection is a key technology for ensuring the quality of steel products and the automation of production. However, in actual industrial scenarios, the complex texture background of steel surfaces often leads to low recognition of tiny defect features and easy confusion, and the full extraction and fusion of multi-scale features remain challenging. To address these issues, this paper proposes a lightweight and high-precision detection model based on the improved YOLOv11n, named YOLOv11-ODF. Firstly, in the backbone network, a C3k2_ODConv module integrating full-dimensional convolution (ODConv) is constructed, which enhances the model’s ability to… More >

Abstract To fully leverage structural health monitoring data for bridge condition assessment, this study proposes a comprehensive evaluation method that integrates static and dynamic indicators using monitoring data, and demonstrates its feasibility through a short-term monitoring-based trend analysis on a newly built bridge. First, based on statistical principles, the Weibull distribution is employed to extract the dead-load component from static monitoring data. Building upon this, a static performance evaluation method is established by incorporating spatial uniformity and trend non-uniformity coefficients.

Abstract The vibration and resonance behavior of steel frame structures are significantly affected by connection flexibility and geometric nonlinearity. Conventional vibration analyses often assume fully rigid beam-column connections and neglect second-order effects, which can lead to inaccurate predictions of natural frequencies and resonance conditions. This study proposes a finite element-based approach for the vibration analysis of planar steel frames with linear and nonlinear semi-rigid connections, explicitly incorporating geometric nonlinearity. Beam-column connections are modeled using nonlinear moment-rotation relationships, while elastic and geometric stiffness matrices, together with a consistent mass matrix, are integrated into the governing dynamic equations.… More >

Abstract This study investigates the wind-resistant performance of a masonry pagoda using ABAQUS. Modal analysis was first conducted to identify the first six vibration modes. Wind speed time histories generated via the harmonic superposition method in MATLAB were converted into wind pressure and applied to the pagoda’s surface. The time-history analysis method was employed to study wind-induced vibrations, obtaining nodal displacement time-history responses. Comparative analyses of structural responses were performed under 0° and 90° wind directions. Finally, Carbon fiber reinforced plastic (CFRP) reinforcement was applied, with post-reinforcement damage analysis systematically compared to the pre-reinforcement damaged state. More >

Abstract Low-frequency ultrasonic array is commonly used to detect interlayer voids located in high-speed railway ballastless track, which is a typical multilayer concrete bonded structure. The difficulty of detection lies in the fact that the total focusing method (TFM) based on a single fixed sound velocity model cannot adapt to the acoustic propagation characteristics of multilayer structures, which is prone to generating artifacts. In addition, the long duration of low-frequency ultrasonic pulses is prone to causing significant deviations in defect localization. To address these issues, a theoretical model of the layered bonded structure is proposed. The… More >

Cold-formed aluminium alloy sections have recently been developed and found to be more cost-effective than conventional extruded sections. Cold-formed metal sections typically contain significant geometric imperfections; the effects of these imperfections have been demonstrated in numerous previous studies and should therefore be considered in analyses.

Abstract Sinking wells (open caissons) are widely used deep foundation structures whose installation by the cut-and-sink method may lead to unintended deviation from verticality due to heterogeneous soil conditions and construction irregularities. While tilting is a frequently observed phenomenon, quantitative criteria for assessing the admissibility of an inclined well after completion of sinking remain insufficiently defined. This study presents a static analytical framework for evaluating stress redistribution beneath the concrete plug of a tilted well. The analysis is based on eccentric vertical load transfer and derives closed-form relationships linking the permissible inclination angle to well geometry… More >

Abstract Basalt fiber (BF), derived from abundant volcanic rock in China, represents a sustainable reinforcement material for pavement engineering, addressing challenges like durability, corrosion, and environmental impact. This comprehensive review synthesizes BF’s properties, including high tensile strength (3000–4800 MPa), thermal stability (−269°C to 700°C), and superior chemical resistance compared to steel or polypropylene fibers. Production involves melting basalt at 1450°C–1500°C, with China leading in resources and standards like JT/T776.1-2010. Applications in asphalt concrete enhance rutting resistance by 30%–50% and fatigue life by 20%–40%, while in cement concrete, BF improves crack resistance and impermeability by 30%–55%. BF More >

Abstract The autonomous grasping of flexible slings is a pivotal challenge for unmanned crane systems, primarily stemming from the slings’ geometric indeterminacy, material compliance under load, and stochastic initial pose relative to the hook. To address this challenge, we propose an intelligent hook system featuring a novel compound mechanical architecture. This architecture integrates a horizontal slewing mechanism for in-plane alignment with a self-locking worm-gear drive for secure grasping. A coordinated control strategy, employing a Fuzzy PID algorithm, ensures robust dynamic performance under variable loading conditions.
