An optimal sensor placement(OSP)method based on structural subsection technique(SST)and model reduction technique was proposed for modal identification of truss structures,which was conducted using genetic algorithm(GA).The constraints of GA variables were determined by SST in advance.Subsequently,according to model reduction technique,the optimal group of mater degrees of freedom and the optimal objective function value were obtained using GA in the case of given number.
