| Abstract: | This paper presents a method for estimating the upper and lower bounds of eigenvalues of structures with uncertainties. The uncertain parameters are described by the convex model. A numerical example of the frame structure is given to illustrate the efficiency of the method. This work is supported by the National Natural Science Foundation of China(No. 19872028). |
