N2 - With the help of PSD algorithm, which makes it possible to do dynamical tests in a static way, an experiment could be tested at multi sites jointly. In order to recover the dynamic characteristics of the whole structure and the substructures, the idea of substructural identification is proposed. Several variations of the methods are proposed to cope with the different situations in this paper. The subspace identification method called MOESP combined with the output inter-sampling scheme is implemented to identify the most complex case. Numerical and physical experiments are conducted in order to extend the capability of the NEESgrid to handle multiple control points in MOST experiments. And the physical PSD experiment is successfully implemented over the NEESgrid network.
