Numerical simulation of the flutter performance of different generic bridge cross sections

Abstract

This paper presents the results of numerical simulation of the flutter performance of different generic bridge cross sections. The bridge flutter assessment has become a major concern in bridge design practice. In the early ages, wind tunnel tests were made in order to assess the aerodynamic performance of bridges. In this paper the flutter performance of different bridge deck sections was investigated by using numerical flow simulation. The detailed comparison of the aerodynamic behaviour of the different cross sections in terms of flutter instability gives the engineers good means to design of bridge structures.
