Course Objectives: To acquaint the students with modern methods of structural reliability analysis based on the theory of probability. The objective of these methods is to evaluate the probability of violation of a limit-state function by a structural system at a given performance/hazard level. This failure probability must be obtained from the various sources of uncertainty/randomness associated with loading parameters, material properties, structural geometry, and boundary conditions, as well as the uncertainty associated with structural models and analysis techniques. The course will cover both the theoretical and computational aspects of structural time-invariant and time-variant reliability analysis. It will also present the formulation of probability/reliability-based design codes. Topical Outline: Introduction to probability theory and random processes. Fundamentals of structural reliability theory. First- and second-order, and simulation methods of reliability analysis. Structural component and system reliability. Reliability sensitivity measures. Time-variant reliability analysis. Dynamic analysis of linear and nonlinear structural systems subjected to stationary and nonstationary random excitations. Performance-based earthquake engineering methodology. Finite element sensitivity and reliability analysis methods. Bases for probabilistic design codes.
