In order to research the damage identification of reticulated shell, the damage identification of reticulated shell was taken on though two-step identification method on the basis of the optimal placement of sensors. The measuring points can be determined according to the optimal placement of sensors, which can be analyzed by the wavelet toolbox of MATLAB, in which make the change rate of modal strain energy the damage index. Then the measuring points of second step can be found. The damage placement can be identified from the second step by the change rate of modal strain energy. The result shows that: the two-step method is feasible.
