It is therefore necessary to adapt these infrastructures or to strengthen their fitness in order to bring their functionality to an appropriate level. One way to do this is to support them with nature-based solutions (NbS). In this contribution, a probabilistic based decision-making tool will be presented that was developed by a group of experts involved in the NATURE-DEMO Horizon project based on the Dutch RAMSSHE€P approach. It allows to efficiently use NbS to protect CI against natural hazards and climate change effects. The challenges in linking natural hazards and NbS with the classic RAMSSHE€P assessment of infrastructure lie in the complexity of natural hazards, their cascading effects, their dependence on the region-specific environment and the natural conditions. In the case of NbS, there are also their temporal and ecological dependencies. The developed decision-making system makes it possible to integrate the effectiveness of NbS and natural hazards into a RAMSSHE€P asset management system that can also be used by regional and supra-regional experts.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 5","pages":"208-215"},"PeriodicalIF":0.0,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cepa.70001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145585055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By capturing high-frequency force fluctuations, load cells enable Ambient Vibration Testing (AVT), which supports the identification of bridge dynamic properties through Operational Modal Analysis (OMA). This dual-purpose use of load cells offers a cost-effective alternative to conventional systems, reducing the number of required sensors and associated data management efforts. A key challenge addressed is the Optimal Sensor Placement (OSP) of load cells to ensure monitoring efficiency while minimizing cost and data overload. To this end, the paper introduces a new OSP algorithm tailored to identify the most informative stays for monitoring. The methodology is validated through a real-world case study involving a cable-stayed bridge with 40 stay cables, where only 8 were instrumented. Results demonstrate the effectiveness of the proposed strategy in capturing both static and dynamic structural behaviours, underscoring its potential for advanced, force-based SHM in cable-stayed bridges.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 5","pages":"42-48"},"PeriodicalIF":0.0,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145585006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finite element model updating (FEMU) techniques provide support in analysing SHM data and enable more reliable previsions about the damage state of monitored structures. Linear modelling assumption is valid while the structure remains elastic but become unreliable after earthquake-induced damage introduces nonlinear behaviour. This study examines how accurately the dynamic behaviour of an infilled reinforced concrete frame building can be simulated, under both ambient noise and low-intensity earthquakes, using linear FEMU techniques. The study starts by analysing the building's real response to ambient and seismic excitations. The research then focuses on the calibration of FE models, using the Particle Swarm Optimization and following three FEMU approaches based on both pre-event modal data and actual time history data from the earthquake. The accuracy of calibrated models in replicating the building's response is evaluated, also focusing on their usefulness for post-earthquake assessment. Finally, optimisation outcomes for the three approaches are compared to assess the strengths and weakness of each.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 5","pages":"95-104"},"PeriodicalIF":0.0,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cepa.3384","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145585009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Network Rail has identified scour as the leading cause of bridge failures in the UK over the past century, with approximately 4500 structures currently at risk. This paper underscores the urgent need for enhanced scour monitoring, a need that is increasingly important due to the rising frequency of flood events driven by climate change. It critically reviews recent advances in scour monitoring technologies, focusing on systems that measure scour depth or detect structural dynamic changes. The review highlights emerging methods including interferometric synthetic aperture radar, water penetrating radar, electromagnetic probes, underwater sonar scanning, as well as vibration-based techniques such as natural frequency, mode shape and operating deflection shape analysis, and indirect approaches using drive-by monitoring, computer vision, and satellite-based synthetic aperture radar. These advancements are needed for developing more resilient infrastructure management strategies and the paper includes a comparative evaluation of the benefits and limitations of each approach.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 5","pages":"282-291"},"PeriodicalIF":0.0,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cepa.70018","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145585084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional structural inspections, relying on contact-based methods, are costly, time-consuming, and pose safety risks for inspectors, with issues of data subjectivity. As a result, there is a need for more efficient, non-contact defect detection techniques. Infrared thermography has emerged as a promising non-destructive testing method, widely used in detecting defects in concrete structures; however, its application in to identify welding defects in steel structures remains underexplored. This study aims to detect welded defects in steel structures swiftly and accurately using infrared thermography. Test specimens with artificial defects were fabricated and evaluated using the passive infrared method. Thermal images and surface temperature data of defective and normal welds were analyzed, with defect presence determined based on the standard deviation of weld temperature. The passive method, conducted outdoors, revealed significant differences in standard deviation between defective and normal parts, demonstrating the potential of infrared thermography for effectively detecting welding defects in steel structures.","PeriodicalId":100223,"journal":{"name":"ce/papers","volume":"8 5","pages":"77-84"},"PeriodicalIF":0.0,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cepa.3375","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145585095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
