Abstract Rutting is a serious issue in asphalt pavement, which may reduce the pavement driving quality and safety. Accurately predicting rutting depth is a crucial task in pavement engineering, providing crucial decision support for asphalt pavement design and maintenance. However, accurate prediction of pavement rutting still remains a significant challenge for pavement engineers. This research first selects the loading number, temperature, dynamic modulus, asphalt layer thickness, and base layer type and thickness as candidate features. Data preprocessing, including outlier handling and feature selection, is then performed. Finally, based on the stacking algorithm, a multi-model fusion approach… More >

Abstract In strong aggressive areas, Indonesian standards specify a maximum penetration of 30 mm. Concrete utilizes sulfate-resistant Portland Pozzolan Cement (PPC) for a target strength of 30 MPa, with and without silica fume and plastic fiber (SR-SFF-sea and SR-N-SFF). Some samples of SR-N-SFF are immersed in the sea (SR-N-SFF-sea), while others are protected (SR-N-SFF-protected). Additionally, concrete using non-sulfate-resistant cement (NSR-sea) with a strength of 20.75 MPa was also evaluated. All samples were subjected to penetration depth testing according to the DIN EN 12390-8 standard, demonstrating that they met the penetration requirements for intense aggression. The study… More > Graphic Abstract

Abstract This study investigates the impact of Type D additive, Plastiment 83 AM, on the compressive strength and microstructure of Portland Composite Cement (PCC) concrete with a target compressive strength of 18.7 MPa, utilizing a mixing, stirring, and treatment model that simulates batching plant conditions. The study investigated additive dosages of 0%, 0.15%, 0.25%, 0.35%, and 0.40%, with stirring durations of 15 min, 2, 4, 6, and 6.5 h. Compressive strength tests were conducted at the ages of 7, 14, 28, 56, and 90 days on cylindrical specimens, and at 24 h for setting time tests.… More >

Abstract Carbon fiber reinforced polymer (CFRP) laminates are widely used in aerospace, new energy, and transportation engineering due to their high specific strength and stiffness. However, interlaminar delamination damage can lead to sudden structural failure, and the occurrence and prediction of such hidden defects are difficult to identify and evaluate using conventional inspection methods. To address this, smart CFRP laminates integrated with fiber Bragg grating (FBG) sensors offer a new approach for real-time structural health monitoring (SHM). Nevertheless, the influence mechanisms of the two integration methods—embedded and surface-bonded FBG sensors—on the static strength and impact resistance… More >

Abstract Hangers play a crucial role in transferring loads in suspension bridges, yet their condition often deteriorates faster than expected due to corrosion and fatigue effects. Premature hanger failure poses serious risks to bridge safety and results in significant economic loss due to frequent replacement and traffic interruption. To address these challenges, this study proposes an integrated framework to evaluate the life-cycle safety and operational cost of bridge hangers. Traffic data obtained from Weigh-in-Motion (WIM) systems are used to simulate dynamic hanger responses. A wire-to-hanger deterioration model is then employed to capture the time-dependent interaction between… More >

Abstract Autonomous truck platooning, as a novel transportation mode, has attracted significant attention due to its potential to improve transportation efficiency, reduce energy consumption, and lower operational costs. However, this emerging mode poses new challenges to the dynamic performance of long-span bridges. This study aims to investigate the impact of autonomous truck platoons on the dynamic performance of continuous beam bridges. Using finite element software to construct accurate vehicle-bridge interaction models, we simulated the dynamic response between vehicle platoons and bridge structures. The study systematically evaluated the effects of four key factors—vehicle speed, number of formations,… More >

Abstract This study presents a comprehensive investigation into the deformation mechanisms of existing metro stations subjected to the simultaneous construction of adjacent foundation pits and underground tunnels. A refined three-dimensional numerical modeling framework is developed to simulate the entire construction process, capturing the complex interactions between excavation activities and station structures. The modeling encompasses deep excavation, side-crossing, and overcrossing passage construction, and the staged installation of support systems. Six construction schemes, varying in excavation sequence, interlayer thickness (clear distance), and passageway layout, are systematically analyzed. Field monitoring data are incorporated to validate the numerical models, enhancing… More >

Abstract The study proposes a low-cost friction damper designed to enhance the seismic performance of buildings, particularly in regions where existing structures lack adequate seismic resistance and conventional friction dampers are cost-prohibitive or require specialized fabrication. Friction dampers are displacement-controlled devices that dissipate energy through constant slip-force action and relative displacement between attachment points, typically ensuring elastic structural behavior under Design Basis Earthquake (DBE) demands and controlled yielding under Maximum Considered Earthquake (MCE) conditions. To address limitations in current practice, the proposed device integrates the damping mechanism of vehicle leaf-spring suspension systems with rotational plate friction… More >

Abstract Using field monitoring data, this study directly compares the stress responses of fatigue-prone orthotropic steel deck (OSD) details with an epoxy asphalt concrete (EAC) overlay during in-service winter and summer seasons. This study was conducted on the E’dong Yangtze River Bridge in China, a cable-stayed bridge featuring a main span of 936 m and an EAC-paved deck pavement. The findings reveal that across all OSD details, stress levels and loading cycles are generally higher in summer than in winter. The most pronounced increase occurs at the rib-to-deck (RD) detail, particularly on the deck plate side.… More >
