“…Para la SHM, el análisis dinámico a la estructura del edificio ante un sismo, se observa diferentes fenómenos como fluctuaciones y variaciones estacionales ocasionados por la temperatura (Tronci, De Angelis, Betti, & Altomare, 2020). En los edificios existen varias causas que llegan a dañarlo y una de esas es el fuego que hace que el concreto pierda su durabilidad y resistencia lo cual se plantea el estudio SHM mediante métodos y la extracción de núcleos del concreto para la evaluación de las propiedades mecánicas y de durabilidad (Aseem, Latif Baloch, Arsalan Khushnood, & Mushtaq, 2019).…”

In the science of monitoring and health maintenance have facilitated damage and defects in buildings by expanding technology through the use of wireless sensors, 3D model, among others, visualize and document results that have encouraged researchers to use powerful tools such as BIM technology, aiming to gain importance due to driving tools that are widely used in the architecture, engineering and construction sector, due to the combination of the results of structural health monitoring (SHM). Eighty articles indexed in Scopus, Ebsco, Scielo and Science Direct databases were reviewed, from the years 2016 - 2021, the following keywords were used to search for information: structural health and BIM technology, Structural Health in building and Bim, Properties of recycled concrete, Health and buildings, Building and BIM technology, Structural health in buildings, structural health of buildings through BIM. Subject area filters were used such as: Engineering, Engineering and Building. Concluding that the union of BIM and SHM technology is the support to establish the situation of the structure, specifying the range of the structural damage and estimating the duration of the structure.

Modal tracking plays a vital role in structural health monitoring since changes in modal parameters help us understand a structure’s dynamic characteristics and may reflect the potential deterioration of structural performance. Although numerous modal parameter estimation (MPE) methods exist, it is not guaranteed that an MPE process will exclude all spurious modes and not lose any physical modes every time over a long-term monitoring period. Relatively large damping of a structure, poor data quality, and significant changes in structural modal parameters may make the estimated modal parameters spurious, missing, or misclassified. It makes long-term modal tracking semiautomated or manual, which constrains timely downstream applications such as anomaly detection, condition assessment, and decision making. This research aims to propose a long-term continuous automatic modal tracking algorithm based on Bayesian inference even when the modal parameters, damping, and data quality change significantly. Bayesian inference is used to determine the physical modes from the results of existing MPE methods. Both the modes identified from the most recent response set and the modal probability model from multiple previous response sets are considered in the Bayesian model to better determine the physical modes from the results of MPE. Moreover, the proposed algorithm requires only three extra hyperparameters compared to general modal tracking algorithms, and they can be quickly determined by a grid search method. The performance of the proposed algorithm is verified by a numerical example and a real-world civil structure Z24 Bridge benchmark.

“…The concept of a non-conventional TMD in a theoretical and experimental study on an innovative seismic retrofit solution realized adding new isolated upper stories on a reinforced old brick masonry building is applied in [21]. It is also worth mentioning the application implemented in an Italian historical tower of a non-conventional TMD [22].…”

A shaking table experiment conducted on a multi-degrees-of-freedom frame structure equipped with a non-conventional tuned mass damper (TMD) is presented. The non-conventional TMD is characterized by a high mass ratio, without adding further structural masses, and is realized via inter-story isolation. The structure top story mass of a four-story steel frame structure is isolated and converted into tuned mass, connecting to the substructure with two high damping rubber bearings placed in series. Aspects related to the dynamic structural response as well as the seismic effectiveness assessment of a non-conventional TMD are addressed. Three structural configurations are tested: the reference four-story structure, the three-story intermediate structure, and the three-story structure equipped with a non-conventional TMD. The input motion conditions considered are: white noise, sine sweep, and natural earthquakes. Through experiments, structural identification is carried out and different dynamic behaviors emerge for the configurations tested. The nonlinear effects provoked on the structure by the adopted isolators are investigated, showing high dissipative capabilities in a wide range of amplitudes of the excitation. It is demonstrated that a non-conventional TMD is a smart control strategy useful for enhancing structural vibration mitigation.
