In this paper, a new data assimilation framework for correcting finite element models from
datasets acquired on-the-fly in low-frequency dynamics is presented. An Unscented Kalman …

A novel framework for hybrid simulation of the seismic response of structures is presented
that employs a mixed displacement and force control strategy. A key feature of this …

In the context of digital twins, it is essential that a model gives an accurate description of the
(controlled) dynamic behavior of a physical system during the system's entire operational …

Tracking the evolution in time of parameters, input and states of a structural dynamic system
is often difficult, since their direct measurement can be problematic or even impossible. It is …

This study presents the implementation of an online model updating algorithm within a full‐
scale hybrid simulation (HS) of a six story, four bay steel moment frame. The experimental …

The study introduces a novel approach for time‐varying reliability analysis of structures
called “hybrid UKF‐PDEM” by integrating the unscented Kalman filter (UKF) and the …

Bayesian filtering aims at sequentially estimating the states and parameters in nonlinear
dynamical systems, and finds applications in a variety of engineering fields. Extended and …

A digital twin should be and remain an accurate model representation of a physical system
throughout its operational life. To this end, we aim to update (physically interpretable) …

Hybrid test method is an effective approach to evaluate the seismic performance of
engineering structures. Particularly, online numerical simulation method (ONSM) based on …

Hybrid simulation combines experimentally testing of physical substructures with
computational simulation of numerical substructures to replicate structural responses under …
