The structural systems in practice are often very complex consisting of iber of components having intricate geometries. Each component may have different failure modes which depend upon variability of material properties, production processes and loadings. Optimisation on design requirements of the complex structural system requires adopting modern computer techniques for evolution and analysis. Finite Element Methods (FEM) is widely used computing technique in engineering design. Since structural analysis tools, such as Finite Element Analysis (FEA) software, are traditionally developed independent of reliability technologies. Consequently, it is common and conventional approach to perform structural analysis and reliability analysis separately, mainly, because established methods and tools for combined analysis are not readily available as yet. Each of the technology domain viz. structural analysis and reliability analysis, however, have established state of the art tools which are under evolution for integrated and combined application in structures reliability analysis and design. These studies shall encompass review of the various available methods & tools for reliability analysis and integration of these techniques to Finite Element Methods to fully utilize the state of art development in the fields of structural analysis and reliability analysis.
