Abstract In this study, artificial neural networks (ANNs) were implemented to determine design parameters for an impressed current cathodic protection (ICCP) prototype. An ASTM A36 steel plate was tested in 3.5% NaCl solution, seawater, and NS4 using electrochemical impedance spectroscopy (EIS) to monitor the evolution of the substrate surface, which affects the current required to reach the protection potential (Eprot). Experimental data were collected as training datasets and analyzed using statistical methods, including box plots and correlation matrices. Subsequently, ANNs were applied to predict the current demand at different exposure times, enabling the estimation of electrochemical More >

Abstract To solve the false detection and missed detection problems caused by various types and sizes of defects in the detection of steel surface defects, similar defects and background features, and similarities between different defects, this paper proposes a lightweight detection model named multiscale edge and squeeze-and-excitation attention detection network (MSESE), which is built upon the You Only Look Once version 11 nano (YOLOv11n). To address the difficulty of locating defect edges, we first propose an edge enhancement module (EEM), apply it to the process of multiscale feature extraction, and then propose a multiscale edge enhancement… More >

Abstract Ultra-high performance fiber-reinforced concrete (UHPFRC) has received extensive attention from scholars and engineers due to its excellent mechanical properties and durability. However, there is a mutually restrictive relationship between the workability and mechanical properties of UHPFRC. Specifically, the addition of fibers will affect the workability of fresh UHPFRC, and the workability of fresh UHPFRC will also affect the dispersion and arrangement of fibers, thus significantly influencing the mechanical properties of hardened UHPFRC. This paper first analyzes the research status of UHPFRC and the relationship between its workability and mechanical properties. Subsequently, it outlines the test… More >

Abstract In recent years, cold-formed steel (CFS) built-up sections have gained a lot of attention in construction. This is mainly because of their structural efficiency and the design advantages they offer. They provide better load-bearing strength and show greater resistance to elastic instability. This study looks at both experimental and numerical analysis of built-up CFS columns. The columns were formed by joining two C-sections in different ways: back-to-back, face-to-face, and box arrangements. Each type was tested with different slenderness ratios. For the experiments, the back-to-back and box sections were connected using two rows of rivets. The… More > Graphic Abstract

Abstract High entropy alloys (HEA) are considered as the candidate materials for the next generation of nuclear systems due to the excellent high temperature properties and radiation resistance. However, for the lack of atomic lattice distortion information from the micromechanical description, the existing simulation methods are difficult to capture the microstructure and damage evolution of the HEA at submicron scale. To address this, we develop the random field theory informed discrete dislocation dynamics simulations based on the results of high-resolution transmission electron microscopy to systematically clarify the role of heterogeneous lattice strain on the complex interactions… More >

Abstract By using the continuous cyclic loading-unloading tensile test method, the nonlinear variation behavior of the chord modulus of mild steel under different temperature conditions was systematically investigated, and the corresponding relationship between plastic strain and chord modulus during the cyclic loading-unloading process was clarified. Through the analysis of test data, the variation trends and quantitative corresponding models of plastic strain and chord modulus at different temperatures were established. The research results show that under constant temperature conditions, as the plastic strain increases to 10%, the chord modulus attenuation process presents a significant two-stage characteristic -… More >

Abstract The shear pin of the friction pendulum bearing (FPB) can be made of 40Cr steel. In conceptual design, the optimal cut-off point of the shear pin is predetermined, guiding the design of bridges isolated by FPBs to maximize their isolation performance. Current researches on the shear pins are mainly based on linear elastic models, neglecting their plasticity, damage, and fracture mechanical properties. To accurately predict its cutoff behavior, the elastic-plastic degradation model of 40Cr steel is indeed calibrated. For this purpose, the Ramberg-Osgood model, the Bao-Wierzbicki damage initiation criterion, and the linear damage evolution criterion… More >

Abstract The penetration of ogival-nosed projectiles into ship plates represents a complex impact dynamics issue essential for analyzing structural failure mechanisms. Although stiffened plates are vital in ship construction, few studies have addressed the issue of model equivalence under penetration loading. This study employs numerical simulation to validate an experiment with an ogival-nosed projectile penetrating a Q345 steel plate. Four equivalent stiffened plate methods are proposed based on the area, flexural modulus, moment of inertia, and thickness. The results indicate that thickness equivalence (DM4) is unsuitable for penetration-loaded stiffened plates, except under low-speed, non-penetrating through impacts, More >

Abstract The impact of longitudinal stiffener configurations on the structural performance of orthotropic steel bridge decks (OSD) was systematically investigated, with emphasis on U-shaped, T-shaped, and rectangular ribs. Finite element analysis was employed to evaluate deformation and stress distribution under three critical loading scenarios: vertical uniform load, vertical eccentric load, and lateral uniform load. Equivalent models ensuring identical steel usage, moment of inertia, and centroid alignment were established to compare five stiffener configurations. Results demonstrate that U-rib configurations exhibit superior performance in controlling local displacements and minimizing stress concentrations. Under eccentric loading, U-ribs significantly reduce deck… More >

Abstract The utilization of high-strength steel bars (HSSB) within concrete structures demonstrates significant advantages in material conservation and mechanical performance enhancement. Nevertheless, existing design codes exhibit limitations in addressing the distinct statistical characteristics of HSSB, particularly regarding strength design parameters. For instance, GB50010-2010 fails to specify design strength values for reinforcement exceeding 600 MPa, creating technical barriers for advancing HSSB implementation. This study systematically investigates the reliability of eccentric compression concrete columns reinforced with 600 MPa-grade HSSB through high-order moment method analysis. Material partial factors were calibrated against target reliability indices prescribed by GB50068-2018, incorporating critical More >
