Dynamic identification and model updating of an eight-storey CLT building
TL;DR: The identified storey masses are indeed realistic and confirm the negligible role of the connections in the low-amplitude dynamic response, and the nonlinear effects of connections over the building response to higher displacements are discussed, providing simplified and practice-oriented correlations for the first natural frequency estimation.
Journal ArticleDOI
Sensitivity analysis of subspace-based damage indicators under changes in ambient excitation covariance, severity and location of damage
TL;DR: The role of damage location in the probabilistic assessment of damage is discussed: a methodological Bayesian approach, based on the results of the sensitivity analysis, is proposed for the development of a structural reliability analysis driven by damage indicators.
Journal ArticleDOI
Time-domain identification of the elastic modulus of simply supported box girders under moving loads: Method and full-scale validation
TL;DR: In this article, the elastic modulus assessment of concrete bridges is derived from an Ordinary Least Square procedure with a Bayesian uncertainty estimation, obtained by approximating the known term of the governing equations due to the travelling force with a square wave signal.

Fragility functions and behavior factors estimation of multi-story cross-laminated timber structures characterized by an energy-dependent hysteretic model:
TL;DR: In this paper, the fragility functions and behavior factors of cross-laminated timber (CLT) structures were assessed and the structures derived from the assembly of single CLT wall panels characterized by diff...

Two-years static and dynamic monitoring of the Santa Maria di Collemaggio basilica
TL;DR: In this paper, the authors reported the outcomes of two years of static and dynamic monitoring from 1/1/2018 to 31/12/2019, and correlated the outdoor temperature and relative humidity to both the amplitude of the cracks and the modal parameters.

Damage identification and health monitoring of structural and mechanical systems from changes in their vibration characteristics: A literature review
TL;DR: A review of the technical literature concerning the detection, location, and characterization of structural damage via techniques that examine changes in measured structural vibration response is presented in this article, where the authors categorize the methods according to required measured data and analysis technique.

Building Information Modeling (BIM) for existing buildings — Literature review and future needs
TL;DR: Results show scarce BIM implementation in existing buildings yet, due to challenges of (1) high modeling/conversion effort from captured building data into semantic BIM objects, (2) updating of information in BIM and (3) handling of uncertain data, objects and relations in B IM occurring inexisting buildings.

Reference-based stochastic subspace identification for output-only modal analysis
Bart Peeters,Guido De Roeck +1 more
TL;DR: In this paper, a novel approach of stochastic subspace identification is presented that incorporates the idea of the reference sensors already in the identification step: the row space of future outputs is projected into the rowspace of past reference outputs.

Monitoring historical masonry structures with operational modal analysis: Two case studies
Luís F. Ramos,L. Marques,Paulo B. Lourenço,G. De Roeck,A. Campos-Costa,João C. Almendra Roque +5 more
TL;DR: The paper addresses two complex case studies of modal and structural identification of monuments in Portugal: the Clock Tower of Mogadouro and the Church of Jeronimos Monastery, in Lisbon.

Analysis of Masonry Structures Without Box Behavior
TL;DR: In this paper, a review of the seismic analysis of masonry structures without box behavior is presented and a comparison is made between pushover methods and non-linear dynamic analysis with time integration.
