“…Porém, alguns autores optam pela utilização de ferramentas que realizam automaticamente essa atualização, como Altunişik et al (2018a), que utilizam do software FEMtools para atualização dos parâmetros de incerteza, baseado no método da sensibilidade, resultando numa diminuição de cerca de 34% na diferença máxima entre os parâmetros. Altunişik et al (2018b) também utilizam o mesmo software, porém com o método Bayesian de estimativa de parâmetros, alcançando redução da diferença máxima de cerca de 12% entre os parâmetros selecionados.…”

RESUMO: A necessidade de monitoramento em estruturas aumenta a demanda por novos métodos de monitoramento, uma vez que ensaios de vibração forçada se tornam inviáveis em estruturas de grande porte. O aumento do acesso a novas tecnologias possibilita o estudo de identificação modal de estruturas utilizando somente carregamento ambiente, seguido de atualização de modelos numéricos e possíveis detecções de danos. Seguindo essa temática, realizou-se um mapeamento sistêmico em base de dados com intuito de caracterizar os estudos relacionados a esse objeto de estudo. Termos lógicos foram inseridos na busca, seguidos de filtragem de aderência de título e resumo. Após a leitura dos resumos dos 1006 artigos resultantes da pesquisa inicial, 76 foram selecionados e analisados conforme a quantidade, ano de publicação e periódico publicado. Entende-se que o crescimento dessa pesquisa se deu após o início da década de 2000, indicando o acesso a processamento como principal fator determinante para aumento do interesse por parte dos pesquisadores. ABSTRACT: The need for monitoring in structures increases the demand for new monitoring methods, since forced vibration testing becomes unviable in large structures. Increased access to new technologies makes it possible to study the modal identification of structures using only environmental loading, followed by updating numerical models and possible damage detections. Following this theme, a systemic mapping was carried out in a database with the purpose of characterizing the studies related to this object of study. Logical terms were entered in the search, followed by title tacking and summary. After reading the abstracts of the resulting 1006 articles from the initial research, 76 were selected and analyzed according to quantity, year of publication and periodical published. It is understood that the growth of this research occurred in the beginning of the year 2000, indicating the access to processing as the main determining factor to increase the interest on the part of the researchers.

“…By using two dynamic modal identification tests before and after the structural rehabilitation, those authors could identify the presence of severe damage in central parts of the south, east and west faades and at the upper part of the tower through a FEM updating process. Altunis ¸ik et al [23] reported an automated FEM updating of an armory building located in Trabzon (Turkey) based upon the minimization of the differences between experimental and numerical natural frequencies. Pachón and co-authors [24] conducted the model updating of a three-dimensional FEM of the historical E. Torroja's bridge in the city of Córdoba (Spain) on the basis of experimentally identified modal properties and a genetic optimization algorithm.…”

Structural Health Monitoring (SHM) based on Automated Operational Modal Analysis (A-OMA) has gained increasing importance in the conservation of heritage structures over recent decades. In this context, finite element model updating techniques using modal data constitute a commonly used approach for damage identification. Nevertheless, the large number of simulations usually involved in the associated minimization problem hinders the application to real-time condition assessment. This is specially critical for historic buildings, where the modelling of complex geometries involves large computational burdens. Alternatively, surrogate models offer an efficient solution to replace computationally demanding numerical models and so perform continuous model updating. In this light, this paper presents a surrogate-based model updating approach for online assessment of historic buildings and its application to a medieval masonry tower, the Sciri Tower in Perugia (Italy). Using modal properties identified by A-OMA, the proposed approach allows the continuous fitting of certain damage-sensitive parameters of the structure. To do so, three different surrogate models are considered, including the quadratic response surface method, Kriging, and Random Sampling High Dimensional Model Representation, and their effectiveness is compared from an SHM perspective. The reported results demonstrate the suitability of the proposed methodology for tracking temperature-dependent intrinsic properties of the tower.
