Thus, the applicability of computer science techniques for SHM applications has attracted the attention of researchers and practitioners in the last two decades. ThisbookaimstodefineandsummarizetheapplicationofdataminingforSHM of infrastructures, including bridges, railway transport systems, wind turbines, buildings, and so on. Data mining comprises selecting the appropriate models and applyingthoseforsearchingpatternsinthefeaturesextractedfrommonitoringdata. Herein, the machine learning algorithms play an important role to unveil hidden patterns. The output of the trained algorithms is used to infer knowledge and to support the decision-making process. Data mining has been a research hotspot in computer science, in the past dec- ades, and it demonstrates a bright future in other fields like civil and mechanical engineering, as it focuses on finding useful information in the data, explaining the theories hidden behind engineering phenomena, which can be used to generate knowledge about the structural state condition. Various engineers from different fields, who are specialized in the data mining, wereinvitedtowriteallthechapters.Therefore,thisbookisexpectedtoprovidea common ground for beginners in the fields of structural health monitoring and structural dynamic analysis.

Thus, the applicability of computer science techniques for SHM applications has attractedtheattentionofresearchersandpractitionersinthelastfewyears,especially to detect damage in structures under operational and environmental conditions. In the SHM for bridges, the damage detection can be seen as the end of a process to extract knowledge regarding the structural state condition from vibration response measurements. In that sense, the damage detection has some similarities with the KnowledgeDiscoveryinDatabases(KDD)process.Therefore,thischapterintends toposedamagedetectioninbridgesinthecontextoftheKDDprocess,wheredata transformationanddataminingplaymajorroles.TheapplicabilityoftheKDDfor damagedetectionisevaluatedonthewell-knownmonitoringdatasetsfromtheZ-24 Bridge,whereseveraldamagescenarioswerecarriedoutundersevereoperational andenvironmentaleffects. · · Keywords Knowledgediscoveryindatabasesprocess Datamining Damage · · · identification Bridgemonitoring Vibrationmeasurements Structuralhealth monitoring M.Silva AppliedElectromagnetismLaboratory,UniversidadeFederaldoPará,R.AugustoCorrêa, Guamá01,Belém,Pará66075-110,Brazil A.Santos FacultyofComputingandElectricalEngineering,UniversidadeFederaldoSuleSudeste doPará,F.17,Q.4,L.E.,Marabá,Pará68505-080,Brazil B E.Figueiredo( ) FacultyofEngineering,UniversidadeLusófonadeHumanidadeseTecnologias, CampoGrande376,1749-024Lisbon,Portugal e-mail:eloi.fi[email protected] CONSTRUCT—InstituteofR&DinStructuresandConstruction,R.Dr.RobertoFriass/n, 4200-465Porto,Portugal ©SpringerNatureSingaporePteLtd.2019 1 Y.L.Zhouetal.(eds.),DataMininginStructuralDynamicAnalysis, https://doi.org/10.1007/978-981-15-0501-0_1 2 M.Silvaetal. 1 Introduction Thebridgesplayacrucialroleinmodernsocieties,regardlessofculture,geograph- icallocation,oreconomicdevelopment.Thesafest,economical,andmostdurable bridges are those that are well managed and maintained.

Overall, the massive data obtained from monitoringsystemsmustbetransformedtomeaningfulinformationtosupportplan- ninganddesigningofmaintenanceactivities,increasethesafety,verifyhypotheses, reduceuncertainty,andwidentheknowledgeandinsightconcerningthemonitored structure. Therefore, the process of implementing an autonomous damage identification strategy for civil, mechanical, and aerospace engineering infrastructure is tradi- tionally referred to as structural health monitoring (SHM) [17]. The SHM pro- cess involves the observation of a structure over time using periodically sampled responsemeasurementsfromanarrayofsensors,theextractionofdamage-sensitive features from these measurements, and the statistical analysis of these features to infertheactualstructuralcondition.Thestructuralconditionevaluationconceptgen- erallyfollowsthedamageidentificationhierarchycomposedoffivelevels(Sect.2.1). Acknowledgingtheexistenceofotherlevelsandtheirimportanceforamorecompre- hensiveinformationonthepresenceofdamage,thischapterposestheSHMprocess mostly in the context of the first level—damage detection.

Therefore, the entire process for damage detectionhassomesimilaritieswiththeKnowledgeDiscoveryinDatabases(KDD) process (Sect.2.2). Basically, KDD is the overall process of extracting and reveal- ingusefulinformationfrommassiverawdatameasurementsandtransformsitinto knowledgefordecisionmaking.Thisprocessisbroadlyappliedinmanyfields,such ashealthcareindustry,financialmarket,advertising,bioinformatics,astronomy,and others[2, 3, 12, 27–29, 35].TheKDDprocesscanbebrokendownintofivesteps [18]:dataselection,datapreprocessing,datatransformation,datamining,anddata interpretationandevaluationforknowledgediscovery.Eventhoughallthosesteps areimportantforknowledgegeneration,thischaptergivesmoreattentiontothedata transformation (Sect.3) and data mining (Sect.4) steps, as those are more directly relatedtothedamagedetection. In most recent years, some concepts of KDD have already been posed in the context of statistical pattern recognition (SPR) paradigm for SHM [17].
