The purpose of this paper is to present a systematic treatment of the reliability of structural systems with multiple limit states. Several performance criteria (e. g. , excessive deflection, first yield, first plastic hinge, plastic collapse) may be selected by the designer in the process of system reliability evaluation, permitting him to exercise full control over the probabilities of occurrence of various limit states. Constraints to limit the system reliability levels with respect to serviceability and/or ultimate conditions may be included if desired. Numerical examples are presented to illustrate the proposed approach.
