Coupled Fluid-Structure Analysis for Estimating and Reducing Tsunami Wave Force Acting on on Bridges

Key Points

• The research aims to analyze tsunami forces acting on bridge structures using advanced simulation techniques.
• Used solids4Foam for elastic analysis of bridges under tsunami conditions.
• Considered three bridge types: box girder, T-girder, and I-girder.
• Incorporated material properties of various bridge components into the analysis.
• Analyzed the effects of fairings on both upper and lower bridge structures.
• Simulations revealed significant reduction of tsunami wave forces and moments with the use of fairings.
• Demonstrated the effectiveness of solids4Foam in performing fluid-structure interaction analysis.
• Findings suggest potential for improved tsunami disaster prevention strategies in civil engineering.
