Part of: Structural Safety Studies

Abstract: The use of finite element methods in structural safety studies is discussed and recent work in the area is briefly reviewed. Formulation for a first-order stochastic finite element method is presented with its application to linear frame structures under static loads. Both structural properties and applied loads are considered to be random. As an example, the reliability of a fixed-end beam with stochastic flexural rigidity and subjected to randomly distributed load is investigated.
