Seismic reliability and sensitivity assessment of Soil-Structure-Foundation Systems

An increasingly important objective for the structural reliability community is the incorporation of advanced reliability methods into current engineering practice. One initiative to address this objective is the development of nonlinear finite element reliability methods. Such methods comprise a combination of static and dynamic nonlinear finite element analysis and reliability algorithms, such as FORM, SORM and simulation. In this article after a brief review of reliability theories we will discuss on capabilities of reliability analysis softwares such as Opensees. This article consists of implementation of analytical tools for stochastic ground motion modeling, finite element response sensitivity analysis, and reliability analysis in order to propagate basic sources of uncertainty related to earthquake loading and material (structural and soil) properties through nonlinear seismic response analysis of SFSI systems.
