Abstract The study of long-term pavement performance is a fundamental topic in the field of highway engineering. Through comprehensive and in-depth research on the pavement system, the previous scattered, one-sided, superficial, and perceptual knowledge and experience are summarized and sublimated into a systematic and complete engineering theory, thereby providing powerful guidance and assistance for the practice of pavement design, construction, maintenance, operation, and management. In this research, the mentoring system deployment technology for automatic monitoring is carried out for long-term pavement performance. By burying a variety of sensors in different parts of the road surface, base,… More >

Abstract As vital hydraulic infrastructures, concrete dams demand uncompromising safety assurance. Seismic effect commonly serves as a potential factor contributing to the damage of concrete dams, making seismic performance analysis crucial for structural integrity. Numerical simulation based on damage mechanics is usually considered as the approach for investigating the seismic damage behavior of concrete dams. To address the limitations of existing studies and extract the key dynamic characteristics of concrete arch dams, a concrete elastoplastic damage mechanics model is adopted, a seismic load input technique involving the viscoelastic boundary along with equivalent nodal forces is generated,… More >

Abstract The large thickness of the common composite precast base slab leads to difficulties in construction through reinforcement installation and pipeline laying. To solve this problem, this paper proposes a lightweight ribbed base slab, reducing the base slab thickness to 30 mm compared to the ordinary precast base slab, adding concrete ribs to improve the mechanical properties of the base slab, and analyzing its damage pattern, stiffness change, and deflection deformation through static loading experiments. Based on the experimental conditions, the effect of concrete rib height, rib width, and top chord reinforcement diameter on the short-term… More >

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 Based on the theory of wave dynamics, this study systematically derives the steady-state analytical solution for the scattering of plane SV-waves by composite lined tunnels in an infinite space using the wave function expansion method. On this basis, a theoretical calculation model for circular composite linings under blast loading is established. Based on the steady-state analytical solution, the δ(x)-function and the Heaviside step function are introduced to construct the Duhamel integral, transforming the transient wave problem into an integral form. By further incorporating the Fourier integral transform, an analytical solution for the transient response around a… More >

Abstract Long-span suspension bridges are inherently vulnerable to earthquakes due to their low stiffness and damping. A novel design, the main-cable-looped (MCL) suspension bridge, features a looped main cable that alters the structure’s load transfer mechanism. The seismic response of this novel bridge type is not well understood, creating an urgent need for investigation to ensure its safety and performance. The global finite element model of this bridge was established by considering the interdependent behavior of the structure and the underlying soil. Based on the design seismic response spectrum, ground motion accelerations were selected, and the… More >

Abstract The present study proposes an autonomous visual inspection system based on Wall-Climbing Robot (WCR), with a view to addressing the shortcomings of traditional building crack detection methods, namely their low measurement accuracy, high manual dependence and insufficient environmental adaptability. The system has been developed to construct a crack recognition model with robust illumination adaptation by fusing the improved YOLOv5s target detection algorithm with the Canny edge enhancement algorithm. The system has been realized as a lightweight deployment on an embedded device (MaixCAM). The robot platform employs a design scheme integrating a dual-chamber negative pressure adsorption… More >

Abstract Engineered Cementitious Composites (ECC) represent an advanced class of fiber-reinforced cement-based materials developed over the past three decades, characterized by remarkable tensile strain-hardening and multiple-cracking behavior. By incorporating hybrid fibers, Hybrid Fiber engineered cementitious composites (HFECC) can be tailored to meet specific engineering demands in terms of strength, deformation, dynamic mechanical performance, and cost-effectiveness. This paper provides a comprehensive review of the critical fiber volume theory, experimental investigations into quasi-static and dynamic mechanical properties, and the structural performance of HFECC. Furthermore, current research gaps and future directions for the development and application of HFECC are More >

Abstract To ensure the safety of the integral hoisting of precast pier boxes for sea-crossing bridges, this study focused on the sidewall height of the pier box and the width of the hoisting sling as core variables, established a finite element model using ABAQUS, and conducted a safety analysis of the hoisting process. The results showed that optimal structural safety and cost-effectiveness were achieved by first casting the concrete base plate of the pier box, then constructing the sidewalls to a height of 500 mm, and subsequently using REE-100T eye & eye round slings for hoisting.

Abstract This study presents a systematic numerical analysis of wind loads on offshore photovoltaic (PV) panels. A computational fluid dynamics (CFD) model, incorporating a free-surface wave boundary condition, is developed and validated against experimental data. Parametric investigations quantify the effects of wind speed, panel tilt angle, clearance, and wave characteristics on the aerodynamic coefficients (drag, lift, and moment). Results indicate that all force coefficients increase with wind speed, with the lift coefficient being most sensitive to wave action. While a larger tilt angle intensifies airflow disturbance and amplifies the coefficients, this effect is more pronounced over More >
