TLDR
In this article, a low magnitude seismic response of a historical masonry structure, the Santa Maria di Collemaggio basilica, was acquired by a complex monitoring system, where ten FBA accelerometers, nine placed on the basilica facade and one on the ground level, recorded respectively the base accelerogram (Input) and the structural response (Output).About:

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.

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.

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.

Assessment of structural interventions using Bayesian updating and subspace-based fault detection methods: the case study of S. Maria di Collemaggio basilica, L’Aquila, Italy
TL;DR: A permanent monitoring system installed in a monumental masonry structure, the basilica of Santa Maria di Collemaggio in L’Aquila Italy, continuously acquires vibration data, which leads to the assessment of a structural intervention using a simple Bayesian approach driven by subspace-based indicators.

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...
