Abstract
  • Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure continues to deteriorate, open grid decks can be used as a cost effective way to rehabilitate structurally deficient bridges. Open grid decks weigh less than conventional reinforced concrete decks and reduce the dead load on a bridge superstructure, thereby increasing the live load capacity. While modern bridge design specifications have evolved to LRFD principles, present design methods for open grid decks are mostly empirical and based on historic practice and performance. Further, fatigue limit states in practice tends to be controlled by cracking in the weak direction, for which no design provisions currently exist. A comprehensive research program was developed to address these issues. The results provide a better understanding of grid deck behavior, and will improve detailing and design provisions.
