Using two degrees of freedom (DOF) experimental flutter derivatives to perform threedimensional
flutter analysis for a cable-supported bridge is a widely practiced method. It is
important to consider the P-derivatives effect to have more accurate analysis for a long
span bridge. Through a case example, this paper studied some of the issues relating to the
P-derivatives effects on flutter. The operational condition in two-DOF experiments was
discussed. One inherent limitation of two-DOF experiments was suggested. Three-DOF
experiment was performed. The effect of the omission of P-derivatives was studied.
