Abstract: This paper studies the static response and reliability of uncertain structures with vector-valued and matrix-valued functions.The finite element analysis method of uncertain structures is based on matrix calculus,Kronecker algebra and pertrubation theory,Random variables and system derivatives are conveniently arranged into 2D matrices and generalized mathematical formulae for perturbatc perturbatcion are obtained.
