Redundancy in Highway Bridge Substructures
The goal of this project is to define rational measures of bridge substructure redundancy. These measures should provide a framework that may be incorporated into the design process to systematically account for system redundancy and the enhanced safety and reliability levels provided by the system as compared with those of the individual members. This goal is accomplished by introducing a tabulated set of system factors that may be used when designing and evaluating the safety of bridge substructures of common configurations, to determine the required component capacity for these substructures as a function of their degrees of redundancy. In this context, a bridge substructure is considered as safe if it provides a reasonable safety margin against ultimate failure (whether due to excessive component damage or overall system collapse) and it does not exhibit excessive displacements that render the bridge inadequate for use. Redundancy of a bridge substructure is defined as the capability of the substructure system to continue to carry loads (vertical and lateral) after the failure of any of its components.
