Summary

Within the last century, there has been unprecedented infrastructure growth, resulting in the construction of bridges, buildings, and tunnels that push the limits of materials and engineering design. As the tide of infrastructure construction recedes, the focus of research is gradually developing toward maintenance. Effective assessment and proactive maintenance are key to ensure the safe operation of infrastructure during its remaining life cycle. Due to the rapid development of sensing technologies and data analyzing methods in recent years, structural health monitoring has been considered as a promising method for the condition assessment of existing infrastructure. At the same time, structural rapid diagnosis and evaluation techniques have also received increasing attention due to their low implementation cost and strong hidden damage detection ability. The main objective of the special issues is to report the latest development in theoretical and experimental investigations of emerging techniques and systems for structural health monitoring and rapid evaluation of civil structures, such as bridges, buildings, and tunnels, etc.

 

Covered topics of this special issue include but are not limited to the latest advancement in theory, techniques, methods, and future trends to advance knowledge in the areas of structural health monitoring and rapid evaluation for infrastructures, such as:

• Advanced Techniques for structural health monitoring;

• Structural rapid evaluation and hidden damage detection;

• Static load testing and vibration testing of structure;

• Probabilistic and non-probabilistic approaches for condition assessment;

• Case study and engineering application.

    Abstract Due to the lack of a quantitative basis for the inspection, evaluation, and identification of existing transmission tower foundations, a new fuzzy comprehensive evaluation method is proposed to assess the reliability of transmission tower foundation bearing capacity. This method is based on the reliability analysis of the transmission tower foundation bearing capacity by analyzing the sensitivity of degradation of detection indexes on the reliability of transmission tower foundation bearing capacity, the weighting coefficient matrix is established about the influencing factors in the evaluation model. Through the correlation analysis between the bearing capacity degradation of the transmission tower foundation and its… More >

    Coupling Effect of Cryogenic Freeze-Thaw Cycles and Chloride Ion Erosion Effect in Pre-Cracked Reinforced Concrete

    Yang Li, Sibo Jiang, Ruixin Lan
    Structural Durability & Health Monitoring, Vol.18, No.3, pp. 255-276, 2024, DOI:10.32604/sdhm.2024.047776

    Abstract Chloride (Cl) ion erosion effects can seriously impact the safety and service life of marine liquefied natural gas (LNG) storage tanks and other polar offshore structures. This study investigates the impact of different low-temperature cycles (20°C, –80°C, and −160°C) and concrete specimen crack widths (0, 0.3, and 0.6 mm) on the Cl ion diffusion performance through rapid erosion tests conducted on pre-cracked concrete. The results show that the minimum temperature and crack width of freeze-thaw cycles enhance the erosive effect of chloride ions. The Cl ion concentration and growth rate increased with the increasing crack width. Based on the experimental… More >

    Research on Fatigue Damage Behavior of Main Beam Sub-Structure of Composite Wind Turbine Blade

    Haixia Kou, Bowen Yang, Xuyao Zhang, Xiaobo Yang, Haibo Zhao
    Structural Durability & Health Monitoring, Vol.18, No.3, pp. 277-297, 2024, DOI:10.32604/sdhm.2024.045023
    (This article belongs to the Special Issue: Health Monitoring and Rapid Evaluation of Infrastructures)
    Abstract Given the difficulty in accurately evaluating the fatigue performance of large composite wind turbine blades (referred to as blades), this paper takes the main beam structure of the blade with a rectangular cross-section as the simulation object and establishes a composite laminate rectangular beam structure that simultaneously includes the flange, web, and adhesive layer, referred to as the blade main beam sub-structure specimen, through the definition of blade sub-structures. This paper examines the progressive damage evolution law of the composite laminate rectangular beam utilizing an improved 3D Hashin failure criterion, cohesive zone model, B-K failure criterion, and computer simulation technology.… More >

    Abstract This study delves into the effects of shield tunneling in complex coastal strata, focusing on how this construction method impacts surface settlement, the mechanical properties of adjacent rock, and the deformation of tunnel segments. It investigates the impact of shield construction on surface settlement, mechanical characteristics of nearby rock, and segment deformation in complex coastal strata susceptible to construction disturbances. Utilizing the Fuzhou Binhai express line as a case study, we developed a comprehensive numerical model using the ABAQUS finite element software. The model incorporates factors such as face force, grouting pressure, jack force, and cutterhead torque. Its accuracy is… More >

    Structural Durability & Health Monitoring, Vol.18, No.2, pp. 181-196, 2024, DOI:10.32604/sdhm.2024.044628
    (This article belongs to the Special Issue: Health Monitoring and Rapid Evaluation of Infrastructures)
    Abstract Pitting corrosion is harmful during bridge construction, which will lead to uneven roughness of steel surfaces and reduce the thickness of steel. Hence, the effect of pitting corrosion on the mechanical properties of cold-formed thin-walled steel stub columns is studied, and the empirical formulas are established through regression fitting to predict the ultimate load of web and flange under pitting corrosion. In detail, the failure modes and load-displacement curves of specimens with different locations, area ratios, and depths are obtained through a large number of non-linear finite element analysis. As for the specimens with pitting corrosion on the web, all… More >

    Assessment of the Influence of Tunnel Settlement on Operational Performance of Subway Vehicles

    Gang Niu, Guangwei Zhang, Zhaoyang Jin, Wei Zhang, Xiang Liu
    Structural Durability & Health Monitoring, Vol.18, No.1, pp. 55-71, 2024, DOI:10.32604/sdhm.2023.044832
    (This article belongs to the Special Issue: Health Monitoring and Rapid Evaluation of Infrastructures)
    Abstract In the realm of subway shield tunnel operations, the impact of tunnel settlement on the operational performance of subway vehicles is a crucial concern. This study introduces an advanced analytical model to investigate rail geometric deformations caused by settlement within a vehicle-track-tunnel coupled system. The model integrates the geometric deformations of the track, attributed to settlement, as track irregularities. A novel “cyclic model” algorithm was employed to enhance computational efficiency without compromising on precision, a claim that was rigorously validated. The model’s capability extends to analyzing the time-history responses of vehicles traversing settlement-affected areas. The research primarily focuses on how… More >
