Abstract:

The effect of hydrodynamic added mass on bridge structures during flooding has been investigated in this work, and its secondary effects on the model dynamic characteristics and natural frequency were studied and developed in both experimental and numerical setup. The theoretical background of the added mass calculations plus numerical simulations have been conducted on both full-scale and small-scale models, while experimental studies have been conducted on only a small-scale model in a tilting flume at the University of Iowa hydraulic lab. After publishing a methodology to calculate added mass of inundated bridges in a journal, this work focused on the effects of the inundation depth with the flow current velocity on the hydraulic added mass quantity. Some preliminary experiments have been conducted, and both numerical and experimental tools and setups have been prepared and developed to perform parametric studies to capture the variability of the hydraulic added mass.
