Why monitor differential camber on hybrid girder-deck bridge systems long term?
Choices
- (A) Unequal creep between concrete girders and timber decks misalign riding surface profiles
- (B) Creep coefficients match across dissimilar materials automatically
- (C) Service geometry tolerances ignore superstructure camber
- (D) Timber never shrinks after installation
Correct answer: (A)
Unequal creep between concrete girders and timber decks misalign riding surface profiles
Explanation
Differential long-term deflection alters drainage and ride quality.
