Structural Health Monitoring of 2D Plane Structures

Applied Sciences, 2021
This paper presents the application of the observability technique for the structural system identification of 2D models. Unlike previous applications of this method, unknown variables appear both in the numerator and the denominator of the stiffness matrix system, making the problem non-linear and impossible to solve.
