1 Load-Induced Bridge Deck Considerations Load-induced bridge-deck deterioration can be attributed either to loads induced by the traffic or by characteristics dependent on the overall bridge system. The problem with this approach is that the bituminous overlay is porous and not waterproof. MCE is analyzed with multiple support ground motion displacement and three-directional time histories. Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book.
This system is typically used for movable bridges and for long-span structures in which a reduced bridge-deck weight is demonstrated to have an economic advantage. These numbers are fairly representative, but should be adjusted for specific locations. In instances of higher creep, the restraining force between the bridge deck and the sup- porting superstructure will reduce significantly, consequently reducing the potential for cracking.
Other factors to carefully consider that make aluminum orthotropic decks different from the steel orthotropic deck system include differences in thermal expansion coefficients, reactions with dissimilar materials, lower modulus of elasticity, and lower fatigue strength of the material, particularly at weld locations. Minimizes intrusion of dissolved chlorides into deck. The disadvantages of basing a specification on this philosophy include an increased design effort, as it is realistic to expect that a greater number of load and resistance factors will be available.
