Structural deformations analysis by means of Kalman-filtering

Abstract

The surveillance of engineering structures like dams is an interdisciplinary task and mainly focused on the assessment of stability and reliability of the objects to be monitored. To show the co-operation of the disciplines involved in a comprehensible manner, it is suitable to use system analysis approaches. Structural deformations analysis by means of system analysis is explained in the following with an example of a dam. The determination of the dam deformations is demonstrated by an integration of computed and measured data by using Kalman Filtering.

O Papel das Covariâncias na Análise de Deformação Aplicada ao Monitoramento Geodésico de Estruturas

“…Uma das alternativas para a análise de deformação de estruturas naturais ou artificiais é por meio do monitoramento geodésico, utilizando, por exemplo, sistemas GNSS (Global Navigation Satellite System) (GULAL, 2013;TIWARI et al, 2018;DURDAG et al, 2018); estação-total (URBANČIČ et al, 2020;ZAMINPARDAZ et al, 2020) ou laser scanner terrestre (ANTOVA et al, 2015;HOLST;KUHLMANN, 2016;JAAFAR et al, 2017). Neste contexto, têm-se diversos estudos recentes a nível nacional sobre o tema (MIRANDA; VEIGA, 2016;FERREIRA;CHAVES, 2017;SAMPAIO et al, 2019;GONÇALVES;MEDEIROS et al, 2020;ALVES et al, 2020).…”

The Application of Kalman Filtering to Predict Vertical Rail Axis Displacements of the Overhead Crane Being a Component of Seaport Transport Structure

“…The use of Kalman filtering for monitoring deformations of engineering objects, such as water dams for instance, is discussed in [9]. The application of the Kalman filter in marine navigation allows the operator, among other aspects, to make decisions which help the watercraft unit to reach safely the target [2, 4, 5, 16, 18, etc.].…”

Modelling Behaviour of Bridge Pylon for Test Load Using Subspace Method

“…Most commonly used was the state-space model (Kalman filter) (Eichhorn, 2006;Kuhlmann, 2003;Mastelić-Ivić and Kahmen, 2001). In papers published by Chatzi andSmyth (2009), andGulal (2013), the state-space model based on the natural laws has been used, i.e. the so-called "white-box", where the system structure and model parameters' values are already known.…”
