Motivated by one of the concepts in the field of health monitoring for structural systems, a damage detection procedure
is developed. In order to perform the system health monitoring, structural health along with sensor and actuator
malfunction must be continuously checked. As a step toward developing a system health-monitoring scheme, this paper
investigated structural damage detection, using a constrained eigenstructure assignment. The proposed damage detection
method is constructed based on a concept of control theory and subspace rotation for two-dimensional (2D)-structural
systems. To demonstrate the capabilities of the developed damage detection algorithm, the behavior of a simulated
degraded braced-frame structure is studied. Using Monte Carlo simulation, the performance of the approach is evaluated.
It shows that the proposed algorithm is potentially promising for application to real cases.
