The application of risk and reliability in the analysis, design, and planning of engineering systems has received worldwide acceptance from the engineering profession. As a result of extensive efforts by different engineering disciplines during the last three decades, design guidelines and codes are being modified or have already been modified to incorporate the concept of risk-based analysis and design.
This paper strives to review that discussion in the context of structural reliability and risk assessment one more time. In particular, we will point out the nature of all kinds of uncertainties in earthquake engineering and
generally categorized them as either aleatory or epistemic uncertainties. Methods for their quantification and mathematical formulations of the structural reliability and calculation of failure probability are then reviewed. Some of these methods are included first and second order approximations, etc.
In general, any engineering has to satisfy more than one performance criterion. The concept used to consider multiple failure modes is known as system reliability evaluation. In this paper, two basic approaches used for system reliability evaluation that are the cut-set or failure mode approach (FMA) and the tie-set or stable configuration approach (SCA) are explained.
