Abstract:
|
In the design process of long-span bridges the consideration of wind effects is a major point
because the extraordinary slenderness of these structures yields a considerable susceptibility for
wind-induced vibrations. Usually, extensive wind tunnel tests are performed to investigate the
aerodynamic behaviour of such structures. Due to increasing computer power, numerical CFD
methods are becoming a serious alternative at much lower costs. In the framework of the research
project NUWIMOD, a discrete vortex method was integrated into the structural analysis program
RM2006. This strong coupling of structural analysis and CFD calculation provides an opportunity
for fast and comprehensive investigation of wind effects. In this paper, aspects of the wind analysis
performed for the Hardanger fjord bridge project are presented.
