A non-probabilistic structural damage identification algorithm based on static strain energy（SSE） is presented in this *** order to overcome the shortcoming of traditional uncertainty quantification methods in modeling nondeterministic parameters,this paper adopts the non-probabilistic interval analysis approach to deal with the system *** the interval bounds of structural parameters and displacement responses are achieved,this approach can effectively predict the range of SSE by interval parameter perturbation ***,a damage criterion,named as SSEPoDE,is proposed by combining SSE with the possibility of damage existence（PoDE）.Meanwhile,a simple but effective method to select the best load case in identification process is also presented.A numerical example is provided to demonstrate the applicability and validity of the proposed method and to solve the damage identification problem in engineering.

A Simplified Method for Analyzing Truss Structure Due to Removal of Members

Journal of Shanghai Jiaotong university(Science) 2003年第2期8卷 118-122页

Based on relating equation group, a simplified method was presented in terms of the matrix displacement method, which can be conveniently used to study the re-distribution of the internal forces and displacement of truss structures due to the removal of members. Such removal is treated as though adding a load case to the original truss, and the re-distribution can be calculated without modifying the original global stiffness matrix. The computational efficiency of the presented method is faster by square times than that of the matrix displacement method. The results from the two methods are identical.
