A hybrid UKF-MGA algorithm for finite element model updating of historical constructions
(2019)
The finite element model (FE) updating is a calibration method that allows minimizing the discrepancies between the numerical and experimental modal parameters. As result, a more accurate FE model is obtained and the ...

Definition and characterization of a historical building by using digital photogrammetry and operational modal analysis : San Juan de los Caballeros Church (Cádiz, Spain)
(2015)
Nowadays, the preservation of the architectural heritage is a fundamental aspect in the cultural development of modern cities. This heritage has to be preserved and different technical analysis are usually necessary to ...

Self-control of a lively footbridge under pedestrian flow
(Víctor Compán Cardiel [etc.], 2015)
In this paper, a case study about a lively footbridge is developed; the vibration levels caused by the pedestrian action are controlled by the change of the modal parameters of the structure due to the pedestrian-structure ...

Estrategias de diseño para garantizar un adecuado nivel de confort en pasarelas peatonales
(2016-05-20)
Es frecuente que las estructuras, una vez realizadas, muestren diferencias, respecto de su concepción original que, en ocasiones, pueden hacer necesaria una intervención posterior con el objetivo de corregir su comportamiento ...

Estimating robust optimum parameters of tuned mass dampers using multiobjective genetic algorithms
(Víctor Compán Cardiel [etc.], 2015)
Tuned mass dampers (TMD) are a well-known control device widely used to control the vibratory problem originated by the pedestrian action on footbridges. The main purpose of this study is the robust multi-objective ...

Actualización de modelos de elementos finitos a partir de los resultados del análisis modal operacional. Aplicación sobre la Capilla del Palacio de Würzburg (Alemania)
(2014)
Una de las primeras dificultades que se plantean a la hora de analizar un edificio histórico es el gran nivel de incertidumbre asociado a multitud de factores condicionantes del comportamiento de la estructura. Pequeñas ...

Ambient vibration testing, dynamic identification and model updating of a historical building. Chapel of the Wurzburg Residence (Germany)
(2015)
One of the main difficulties that can be detected in a historical building structural analysis is the high level of uncertainty associated with many factors affecting the behavior of the structure. Slight modifications ...

Robust improvement of the finite-element-model updating of historical constructions via a new combinative computational algorithm
(Elsevier, 2024-04)
Finite-element-models are usually employed to simulate the behaviour of historical constructions. However, despite the high complexity of these numerical models, there are always discrepancies between the actual behaviour ...
