） Abstract： With numerical analysis the feasible bending displacement mode is expanded to get full information of parameters
Then, the method of modal strain energy is used for structural damage identification of the plane frames and plate structures based on full information of DOFS obtained by the mode shape expansion
Compared to the theoretical identification results of full information of DOFS, result indicates that the method of modal strain energy based on mode shapes expansion could be used to identify damage of the plate structures with some errors when the information of DOFS is incomplete
