Potential Benefits
The obtained research findings will facilitate the tornado-resistant design of new bridges. They will facilitate the reinforcement of existing bridges to be tornado-resistant. This will eventually prevent bridges from failure during tornado incidents to enhance the safety of highway or railroad bridges.
Brief Description of Research Project
Tornadoes have destroyed or severely damaged a number of bridges in the USA. To prevent bridges from being severely damaged or destroyed during future tornado incidents, it is imperative to characterize the wind effects induced by tornadoes on bridges and determine the design tornadic wind loads for bridges. This project will characterize the wind effects of tornadoes on bridges using Computational Fluid Dynamics (CFD) simulations, and modify the equations for calculating the design wind pressure on bridges.
