Damage Modeling, Monitoring, and Assessment of Bridge Scour and Water Borne Debris Effect for Enhanced Structural Life (C19.2020)
Many Bridges failed during flooding events due to bridge scour or waterborne debris impacts or their combinations. It is essential to evaluate the risk of bridge failures before flooding and make predictive management to ensure the safety of the bridge. The present study is proposed by an interdisciplinary team, and the goal is to establish a systematic framework to apply analytical, computational, and experimental techniques to evaluate these effects on future life of bridges. Surveys, literature reviews, and simulations are also performed to evaluate possible methods to reduce the damages from scours and debris impacts. After collecting information on flooding damages to bridges and failures due to bridge scour and waterborne debris effects, the team will collect existing flooding, scour and waterborne debris related data in the New England region including historical flood data from different measuring stations, such as those from NOAA and the U.S. Geological Survey (USGS). Field monitoring will be implemented on-site to measure water speed, water level, scour depth, as well as displacements and accelerations of bridge components to evaluate scour effects. Statistical analysis will be performed to assess the probability of failure of the bridges using flood data. Data-driven approaches as well as vehicle-bridge-scour-debris interaction based numerical simulations will be implemented to find correlations between the key flooding and scour parameters and the structural responses (displacements and accelerations). The time-variant bridge system model will be updated, as well to consider deterioration and scour damages. Resilience options will be evaluated, as well.
