Numerical study on Modal Analysis of a typical bridge section with the influence of Aeroelastic effect

Abstract

Due to the increase in the number of vehicles, transportation management is achieved through the construction of bridges. This article discusses the vibrational effect in the design of bridges. In the structural design of the bridges proper planning is necessary, as gusts may occur, leading to aeroelastic instabilities. In this article a typical bridge is designed using the design software CATIA and a numerical simulation using analysis software ANSYS. Further, the aeroelastic phenomenon involved in coupling of Fluid Structure Interaction is discussed. The results of Mode shape show vortex-induced vibrations which can lead to Flutter.
