An in-time damage identification approach based on the Kalman filter and energy equilibrium theory

Abstract: Abstract:In research on damage identification, conventional methods usually face difficulties in converging globally and rapidly. Therefore, a fast in-time damage identification approach based on the Kalman filter and energy equilibrium theory is proposed to obtain the structural stiffness, find the locations of damage, and quantify its intensity. The proposed approach establishes a relationship between the structural stiffness and acceleration response by means of energy equilibrium theory. After importing th… Show more

“…Additionally, some methods have been combined with the Kalman filter to enhance the ability to detect structural damage. Based on energy theory, a relationship between the structural stiffness and acceleration response was generated by using Kalman filter, and this relationship was applied to fast detect the damage of structures [34]. An extended Kalman filter-based artificial neural network was proposed to detect the damage in bridges caused by the changes of environmental temperature [35].…”
