     the problem of sensor placement is a fundamental part of dynamic testing, modal identification, damage detection and structural health monitoring (shm) of structures. this paper is considered with the problem of optimal placement of sensors on a strap-braced cold formed steel frame in order to identify modal parameters of the frame for the purpose of structural health monitoring. several optimal sensor placement methods are applied to the verified numerical model of the strap braced cold formed steel frame and different criteria are employed to evaluate the performance of the methods. the results show that among the methods, effective independence and effective independence-driving point residue methods provide commendable methodologies for optimal sensor placement of the frame. they have the ability to guarantee the criteria, as well as the deployment of sensors in a uniform fashion for the frame.
