Abstract
This report extends the two-state elements, survival and failure, to the case in which these elements have two or more possible partial damage states. Several schemes are explored for defining and evaluating the condition of an entire network as a single scalar value, given the conditions of the network's elements. The schemes are developed to facilitate seismic risk analysis. Damage states used in the study are: no damage; moderate damage; heavy damage; and total destruction/inoperative. A series system is presented in which three different methods for describing the network state as a function of the element's states are shown. Also described are three schemes analogous to the series system for which a system in parallel is developed. Finally, the report contains examples and results of complex systems and describes the concept of tie sets as a tool for analyzing networks.
