Abstract Butt welding technology is widely used in critical fields such as architecture and civil engineering, pipeline and energy transmission, pressure vessels, shipbuilding and marine engineering, rail transit, and aerospace. However, defects such as weld misalignment are common during fabrication, and systematic research on the influence of misalignment magnitude on the fatigue life of welded structures remains inadequate. To clarify this influence mechanism, this study employed a 3D fatigue finite element (FE) method to simulate and compare three butt-welded specimens (one without misalignment and two with different misalignments). First, a 3D non-steady heat transfer analysis was… More >

Abstract Brick-concrete recycled aggregate concrete (BCRAC) represents a crucial pathway for the resource utilization of construction solid waste. To elucidate the effects of recycled brick aggregate (RBA) particle size and replacement ratio on the fracture properties of BCRAC, this study employed continuously graded recycled concrete aggregate (RCA) as the baseline material. Fracture tests were conducted by replacing RCA with 5–10 and 10–20 mm RBA through size-by-size substitution at replacement levels ranging from 0% to 50%. The results indicate that, with increasing RBA replacement ratio, the descending branch of the load-displacement curve of BCRAC becomes steeper and… More >

Abstract Simply supported–continuous girder bridges are widely used in high-speed railways in northwestern China, where large temperature variations and frequent seismic activity coexist. Existing studies have primarily examined temperature and seismic effects separately, whereas research on their combined effects has mainly focused on highway bridges. This study develops a track–bridge integrated finite element model and performs dynamic time-history analysis to investigate the structural responses under combined temperature and seismic loading. The results show that the initial stress state induced by temperature loading significantly alters the stress distribution during seismic events, with the expansion-joint region identified as… More >

Abstract To address the engineering challenges posed by the susceptibility of raw data collected by bridge health monitoring systems to interference from complex environmental noise in real-world applications, as well as the severe mode aliasing issues associated with Empirical Mode Decomposition when processing non-stationary signals, this paper proposes a joint denoising and feature separation technique that integrates the Golden Jackal optimization algorithm with multivariate variational modal decomposition and wavelet thresholding. Addressing the shortcomings of traditional variational modal decomposition—which relies heavily on manual parameter tuning—this framework introduces the Golden Jackal optimization algorithm.

Abstract Emergency composite cableway bridges offer lightweight, high-strength construction with rapid installation, yet their flexible structure and extremely low natural frequencies make them susceptible to wind-induced vibrations. This study analyzes the vibration characteristics of an emergency composite cableway bridge designed to meet specific static load requirements. A finite element model was developed using ANSYS to investigate the impact of the number and angle of wind-resistant cables on dynamic performance. Modal analysis without wind-resistant cables reveals a first-order fundamental frequency of only 0.0125 Hz and a tenth-order fundamental frequency of 0.0649 Hz—significantly lower than conventional cableway bridges,… More >

Abstract The paradigm in seismic design is shifting from preventing structural collapse to enabling rapid post-earthquake functional recovery, positioning replaceable structural components as a key development trend. These components offer a significant advantage: following an earthquake, only the pre-designed replaceable elements need to be swapped out to restore the building’s overall functionality, thereby enhancing seismic resilience and reparability.

Abstract In urban areas, deep and large foundation pits often require dewatering during excavation. This process alters the free displacement field of surrounding soils, potentially causing uneven deformation in adjacent tunnels. To address this issue, the unloading of soil excavation and dewatering around the pit foundation are taken into consideration, which is clearer to actually foundation pit excavation. Firstly, utilizing the Mindlin method and the effective stress principle, the extra stress along the tunnel's axis is detected induced by the excavation and dewatering of foundation pits. Subsequently, the current tunnel is conceptualized as a Timoshenko beam… More >

Abstract Accurate state assessment and remaining useful life (RUL) prediction for ship propulsion systems are critical in ensuring maritime safety, reducing maintenance costs, and enhancing transportation network resilience. Although Gaussian process methods are widely used for RUL prediction, existing models often rely on deterministic assumptions or fixed kernel functions, which struggle to fully capture the nonlinear, multi-scale, and stochastic characteristics of degradation in ship propulsion components. This paper proposes an automatic kernel selection framework based on Bayesian tree structures, integrated with Gaussian Process Regression (GPR), for probabilistic degradation modeling and RUL prediction of critical components.

Abstract Microbially Induced Carbonate Precipitation (MICP) is an environmentally friendly technique for sandy soil stabilization. However, the cementation performance is governed by multiple coupled factors and complex experimental procedures, making accurate prediction challenging. In this study, a dual-objective XGBoost prediction model suitable for small-sample scenarios is developed from 77 sets of laboratory data to rapidly estimate unconfined compressive strength (UCS) and calcium carbonate content (CCC) separately. A mechanism-guided feature engineering strategy is adopted to construct three cross features, including urease activity coupled with curing time, calcium carbonate content combined with curing time, and urea-calcium concentration, together… More >

Abstract Pipe cooling is a primary method for temperature control in mass concrete construction. The optimization of cooling pipe layout in practical engineering calls for the development of new simulation methods that combine computational accuracy with efficiency. This study presents a mesh-independent method for thermal analysis of pipe cooling in mass concrete structures. Two energy balance equations are established for the water pipe, modeled using lattice elements, and for the concrete, modeled with hexahedral solid elements. The local thermal non-equilibrium (LTNE) effect is captured through heat exchange between the two domains, facilitated by spatial topological mapping. More >

Abstract During winter construction in cold regions, ultra-high performance concrete (UHPC) is susceptible to early-age freeze-thaw cycles caused by improper curing or sudden cold waves. This study investigates the damage evolution of UHPC under freeze-thaw cycles and the subsequent strengthening effect of carbon fiber reinforced polymer (CFRP). Early-age (7-day cured) UHPC specimens were subjected to coupled freeze-thaw and chloride salt (5% NaCl) exposure. Damage was characterized by ultrasonic wave velocity, compressive strength, and SEM-EDS analysis. Results show that as the number of freeze-thaw cycles increases, mass loss reaches 1.35% at 150 cycles, while wave velocity decreases… More >

Abstract The structural performance of reinforced concrete critically depends on the integrity of the bond at the rebar–concrete interface. Reliable nondestructive evaluation (NDE) methods capable of assessing interfacial degradation remain limited, particularly when conventional ultrasonic imaging techniques fail to resolve subtle bond deterioration. This study presents a parameter-based ultrasonic evaluation approach based on shear-wave full-waveform inversion (SH-FWI) for characterizing rebar–concrete interfacial degradation. Ultrasonic shear-wave measurements acquired using a commercial array system (A1040 MIRA) were processed through a two-dimensional SH-wave inversion framework to reconstruct spatial distributions of shear-wave velocity and density within concrete.

Abstract To reduce self-weight, accelerate construction, and lower costs of steel-concrete composite beams, steel fiber-reinforced concrete (SFRC) was combined with steel to develop a novel steel-SFRC composite beam system. To evaluate the ultimate flexural load-bearing capacity of steel-SFRC composite beams, a three-dimensional finite element model (FEM) was established. Compared with test results, the simulated failure modes agreed well with the experimental observations, and the predicted ultimate flexural capacities ranged from 89% to 97% of the test values, validating the accuracy and reliability of the FEM.

A transfer function formulation is developed to reconstruct contact-point bridge accelerations directly from simulated multi-degree-of-freedom vehicle acceleration measurements, followed by band-pass filtering around the first natural frequency and Hilbert transform envelope extraction to obtain spatial amplitude distributions along the bridge span. The framework is evaluated using a coupled vehicle bridge interaction model under both idealised (zero road profile) and realistic (ISO Class A and Class B) conditions, considering healthy and bearing-damaged scenarios across a range of… More >

Abstract Long-term guided-wave structural health monitoring accumulates large volumes of sensing data, but dense damage labels are rarely available in field deployment. Unsupervised reconstruction-based detection methods, which identify damage through reconstruction discrepancy, are therefore appealing for their ability to learn directly from unlabeled data. However, environmental and operational variations and mixed adjacent-stage samples in transition windows both degrade unsupervised detection performance. Regularization offers a principled way to improve the robustness of unsupervised detection against such confounding variations, but its effect on fine-grained, transition-level detection has not been systematically studied.

Abstract The use of self-compacting concrete (SCC) in structural elements has significantly increased in recent years due to its superior fresh properties, including high flowability, ease of placement, and ability to consolidate without vibration, making it particularly suitable for complex and densely reinforced structures. However, despite these advantages, SCC presents certain limitations when exposed to fire, which is considered one of the most severe threats to structural safety. This is mainly due to the lack of comprehensive understanding and design guidelines regarding its behaviour under elevated temperatures, particularly at the structural element level.
