However, research on connectivity assessment of bridge networks considering spatial correlations associated with flood intensities is scarce in the literature. When quantifying the spatial correlation of flood intensities, modeling based on the stream distance rather than the Euclidean distance is required, taking into account that river flow is restricted only within the stream network. To achieve this purpose, a novel methodology is proposed to evaluate the spatial correlation of a stream network based on a geostatistical linear model and stream network covariance models. In addition, this study considers the spatial correlation of seismic hazard intensity. With the proposed method, it is possible to identify which bridges play an important role in ensuring the connectivity of the road network under multiple hazards, i.e. flood and seismic. As an illustrative example, the proposed method is applied to a hypothetical bridge network in Kumamoto Prefecture, Japan. The results demonstrate that improved network connectivity can be achieved by implementing a relevant retrofitting strategy for important bridges.Keywords: Network connectivitybridgesspatial correlationmultiple hazardsflood hazardseismic hazardMonte Carlo simulation Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by JSPS KAKENHI (Grant number: 23H00217) and JST-JICA SATREPS (Grant ID: JPMJSA2009).","PeriodicalId":49468,"journal":{"name":"Structure and Infrastructure Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135186236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the construction cost of implementing this advanced technique to real-life buildings compared to the conventional ones remains a debatable topic, and a research problem to examine. Therefore, the present study focuses on assessing the short- and long-term cost-benefits of base-isolated buildings vis-é-vis fixed-base buildings over their service life. Notably, the benefit-cost analysis methodology prescribed in FEMA-356 is utilized to quantify the economic consequences of natural calamities on the base-isolated building. Various aspects, such as structural responses, damage vulnerability, collapse probability, and occupancy rate are thoroughly analyzed. A real-life mid-rise reinforced concrete building in the Indian subcontinent, having double-curvature friction pendulum bearings (FPBs) at stilt level is deliberated in this study. A series of quasi-static and nonlinear time-history analyses are carried out based on the recently drafted Indian seismic code for base isolation to comprehend the improved performance of the FPB-isolated building. Additionally, two fixed-base buildings are designed with an aim to make their performance almost at par with the base-isolated building, and then to assess the cost implications of attaining such comparable performance. The outcomes of this study, particularly the structural performance enhancement and cost benefits, will assist both decision makers and structural designers to have a persuasive opinion on the better adaptability of the base isolation technology for improved seismic resistance and financial outlooks associated thereof.Keywords: Friction pendulum bearingIndian seismic code and provisionsperformance-based seismic designBenefit-cost analysisLoss estimationPassive vibration control Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThe financial support extended by M/s Resistoflex Dynamics Private Limited, Sector 2, NOIDA, Uttar Pradesh (U.P.) – 201 301, India in conducting the present study is gratefully acknowledged.","PeriodicalId":49468,"journal":{"name":"Structure and Infrastructure Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135290602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a practical example, this article presents an ICT-based bridge remote monitoring system called the \"Intelligent Bridge,\" which allows real-time monitoring and control during extreme events such as earthquakes and typhoons. The Intelligent Bridge comprises a stand-alone monitoring system and a web-based internet monitoring system for bridge maintenance, which is introduced as an intelligent structure integrated into the intelligent bridge system. To verify the validity of the proposed system, it is investigated the ability to adjust cable forces on a 2-span continuous cable-stayed bridge model to control its structural performance. The development of an intelligent bridge system represents a significant advancement in bridge engineering and has the potential to improve the safety and longevity of bridges, particularly in areas prone to extreme environmental events.

Machine learning (ML) models use historical bridge performance data to learn and predict performance. However, in many agencies, the condition history of bridges is limited and does not go beyond a few years. The question, therefore, is, to what extent does condition history help us make better predictions? To address this question, a ML model was developed that analysed more than 600,000 bridge decks with 27 years of condition history. Two data selection methods were designed: non-overlapping and overlapping data. The non-overlapping data are typically used to train the model. The overlapping data introduced in this study uses the data more efficiently for model training recognising that strings of historical data convey more information. Longer term predictions were found to be positively impacted by every additional year of condition history. Short-term condition prediction (one or two years) does not need significant historical data. It was also found that overlapping data, compared to non-overlapping data, produced larger training samples and had higher prediction accuracy in the majority of experiments, but at the cost of higher running time due to a larger sample size.Keywords: Artificial intelligencebig datainfrastructure asset managementmachine learningbridge structure deteriorationbridge conditionneural networkperformance prediction Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":49468,"journal":{"name":"Structure and Infrastructure Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135725934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conclusion, downstream of all these analyses and with the comparison of the real-life experiments, was to allow a limited extension of the useful life of the bridge, even with some reductions in the safety factor, respecting a reduction in the speed of railway trains and prescribing continuous monitoring of the bridge. In this context, all the test evaluations, combined with the surveillance/monitoring, and joined with an important numerical modelling activity, lead to the concept of “structural augmentation” of the bridge for service life extension purposes.

To achieve this, first, synthetic signals resembling the monitored acceleration are constructed and processed using four time-frequency techniques. The accuracy of IF tracking, signal reconstruction, and representation resolution are obtained and compared between these different time-frequency techniques. Subsequently, the monitored vertical and torsional accelerations from the Humber Bridge are analysed using the Fourier synchrosqueezed transform and the improved multisynchrosqueezing transform. This allows for the reconstruction of individual acceleration components along with the corresponding variation of the natural frequency. The magnitude of each component of the monitored acceleration is then obtained. The relative importance of modes in the monitored acceleration is evaluated based on the acceleration root mean square. This study presents a novel approach that involves reconstructing the monitored acceleration and assessing the magnitude of individual components of the monitored data of the bridge under operational conditions using the advanced time-frequency method. The method is particularly suitable for addressing multicomponent monitored data and is expected to benefit future practical research in the bridge health monitoring field.Keywords: Time-frequency analysisreconstruction of accelerationinstantaneous frequency trackingresolution of representationroot mean squareoperational conditionssynchrosqueezed transform AcknowledgementsThe author expresses his gratitude to Dr. Ki Young Koo at the University of Exeter for providing the monitored data and contributing to the code.Disclosure statementThe author reports there are no competing interests to declare.","PeriodicalId":49468,"journal":{"name":"Structure and Infrastructure Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135934370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study discusses the characteristics of half-joint bridges, also known as Gerber beam types. These designs, originating in the late 1800s and commonly utilized from the 1950s to the 1970s, exhibit an isostatic structure. While they are easy to design, typically featuring pairs of piers with symmetrical cantilevers and two or more suspended spans, they often suffer from weakening of the half joints (saddles), necessitating structural consolidation. Designers have proposed several solutions to strengthen this type of bridges and the approach presented in this paper focuses on cost-effectiveness and efficiency. It involves a gradual demolition of longitudinal strips on the RC slab of suspended beams, followed by the installation of new steel beams to create a mixed RC-steel system. The application of this method is illustrated in a double-pier bridge spanning the Arno River, Italy. The bridge’s rehabilitation required a complete closure of the traffic road for twelve weeks, followed by alternating traffic for twenty-four weeks. The paper discusses both the design and construction aspects of the proposed intervention, considering costs and implementation time. Furthermore, a low-cost health monitoring procedure is briefly introduced.Keywords: Brittle collapsecomposite steel structuresconstruction phasesgerber beamhealth monitoring strategylow-cost rehabilitationRC bridge strengtheningroad bridge AcknowledgementsThe authors thanks to C.

The arrangement and design parameters of these frames are mentioned in some references, but there is no probabilistic assessment of collapse risk based on various collapse uncertainties. To evaluate the probability of collapse and margin of safety, eighteen suspended zipper-braced frames with different geometry parameters in the most severe seismic design category (Dmax) have been designed. The designed frames were modeled in OpenSees software by considering the effect of gusset plate connections and evaluated by performing more than 15,800 dynamic and nonlinear static pushover analyses using FEMA P695 methodology. Total collapse uncertainty is considered in the evaluation of the probabilistic behavior of frames. The results show that the adjusted collapse margin ratio (ACMR) of designed frames by considering the total collapse uncertainty of 0.726 and 0.529 is 27% and 64% higher than the acceptance criteria, respectively. The results also indicate that a response modification coefficient of much more than 6 can be used for the economic design of long-period suspended zipper-braced frames.Keywords: Collapse uncertaintyincremental dynamic analysesprobabilistic evaluationsafety margin ratiosuspended Zipper-Braced frame Disclosure statementThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.","PeriodicalId":49468,"journal":{"name":"Structure and Infrastructure Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136158868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
