Abstract: A reliability analysis method of stiffness of large and complex structure systems is proposed,and relative significance is introduced as a criterion to enumerate significant random variables.Simplifications of limit state functions and selections of intemolation points are stu-died through numerical examples.Thus,an unit stiffness reliability analysis method is estab- lished for general and special engineering problems,and this method can be extended to strength reliability analysis.

Key words: reliability analysis, stiffness, random variables, critical loading
