Progressive Collapse and Structural Robustness of Bridges

Article Preview

Abstract:

Structural robustness has been recognized as a fundamental property of structural systems to prevent the occurrence of disproportionate failure events and progressive collapse. Bridges are primarily horizontally aligned structures with one main axis of extension. Only a few of many modern building codes provided methods can be applied to bridges. In this paper, associated strategies to enhance collapse resistance can be addressed by controlling abnormal events, individual local element behavior and global system behavior. Various design methods towards preventing progressive collapse such as non-structural protective measures, local resistance, multiple load paths or structural segmentation are applied to bridges. The suitability depends on the type of bridge structures.
