The stability of the cable supported bridge deck during wind and traffic

With nowadays trends of elongation of span length in bridge structures, they are becoming more and more sensitive to wind loads, therefore analysis of their aero elastic stability is of great concern. These structures have low eigen frequencies and low damping, which makes them highly susceptible to actions of the wind. Studies of flow-induced vibrations, which are excited by complex interaction between airflow and moving bridge girder, are of great importance for estimation of dynamic response of bridge structures
