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...

Time Domain Identification of Frames under Earthquake Loadings
TL;DR: In this article, the adaptive identification method and the nonlinear system identification technique through numerical simulation on seismic response of building structures are examined, and two parameter adaptation algorithms in recursive identification methods are discussed: recursive least square algorithm with constant trace and adaptive fading Kalman filter method.

Equivalent linearization for systems subjected to non-stationary random excitation
Wilfred D. Iwan,A.B. Mason +1 more
TL;DR: In this article, the eauivalent linearization method was applied to the general problem of non-linear discrete systems to non-stationary random excitation, and conditions for minimum equation difference were determined which do not depend explicitly on lime but only on the instantaneous statistics of the response process.

Experimental and numerical modal analyses of a historical masonry palace
TL;DR: In this article, the authors presented the determination of modal properties of a historical masonry palace built between 1861 and 1865 in Istanbul, where both an experimental and a numerical study have been performed.

Dynamic identification of historic masonry towers through an expeditious and no-contact approach: Application to the “Torre del Mangia” in Siena (Italy)
TL;DR: In this paper, a multidisciplinary approach where laser scanner survey, radar interferometric monitoring and finite element numerical modeling are used for expeditious and no-contact dynamic identification of monumental masonry towers is presented.

Impact of traumatic loss on post-traumatic spectrum symptoms in high school students after the L'Aquila 2009 earthquake in Italy

TL;DR: Having experienced the loss of a close friend or a relative in the framework of the earthquake seems to be related to higher PTSD rates and more severe symptomatology, highlighting the need to carefully explore adolescents exposed to a significant loss as consequence of an earthquake.
