• Abstract:
  The objective of this research was to develop the deterioration curves of the primary bridge superstructure designs to understand their characteristics over time. The research methodologies involved a meticulous data collection and processing step, analyzing Ohio's historical bridge inventory dating back to the mid-1980s, followed by deterioration model development and comparative analysis. A regression nonlinear optimization (RNO) model was applied to develop deterioration curves for each superstructure type, employing Python scripts for plotting the best-fit polynomial regression curves and MS Excel solver for Markovian transition probabilities. Furthermore, a comparative analysis was conducted, examining deterioration characteristics among different superstructure designs for each maintenance responsibility (e.g., state, county, and city/municipality) and average annual degradation rates over a 5-year age range. The comparison of deterioration curves for six bridge structure types owned by the state DOT indicates that stringer beam and slab designs demonstrate superior durability over time. However, box beam designs exhibit rapid deterioration as they age. In county and city/municipality settings, slab designs generally show more gradual deterioration, while frame designs display early deterioration patterns. Data also suggests variations in degradation rates among different design types, emphasizing the influence of construction quality and design longevity on bridge performance.
