The paper presents an approach to track sudden changes in stiffness of structural systems
exposed to earthquake induced base excitations. Such sudden changes in the stiffness …

The extended Kalman filter is a useful tool in the research of structural health monitoring and
vibration control. However, the traditional extended Kalman filter approach is only applicable …

Extended Kalman filtering with unknown input (EKF-UI) is often used to estimate the
structural system state, parameters and unknown input in structural health monitoring …

Accurate and real-time information of structural states and earthquake input is the
prerequisite for structural seismic safety assessment and vibration control. When the …

Periodic health assessment of large civil engineering structures is an effective way to ensure
safe performance all through their service lives. Dynamic response‐based structural health …

An objective of the structural health monitoring system is to identify the state of the structure
and to detect the damage when it occurs. Analysis techniques for damage identification of …

System identification refers to any systematic way of deriving or improving models of
dynamical systems through the use of experimental and field testing input-output data. In the …

The conventional parameter identification process generally assumes that parameters
remain constant. However, under extreme loading conditions, structures may exhibit …

In this paper, a three-stage Kalman filter is proposed for identifying both the load and the
unknown parameters in structures. To suppress the load drift caused by using only …
