Theoretical Model and Method for Self-Excited Aerodynamic Forces of Long-Span Bridges

This paper introduces theoretical model and methods for computational- ly determining aerodynamic forces of long-span bridges under wind-induced vi- bration, and emphasis is placed on self-excited aerodynamic force model and nu- merical identification of model's parameters, flutter derivatives. Through a serious analysis of the thin-plate cross section, the H-shaped section, and the closed box section, the main problems and the key prospects are concluded.
