Analysis of Complex Proper Orthogonal Decomposition for Fluctuating Wind Pressure Field Acting on the Surface of Oscillating 3D Square Prism

Part2 Contribution Ratio and Motion-Induced Wind Force

Abstract

In this paper, the analysis is conducted more to aim at the reverse-symmetric mode which is shown in the part 1 of these papers. A reverse-symmetric mode and Variation Coefficient of Overturning Moment for the normalized wind velocity show a similar tendency, and this tendency vouches a physical effect to increase the response from the contribution rate. Furthermore, the motion-induced Wind Force Coefficient is defined, and the coefficient of wind force has agreement with Motion-induced Wind Force Coefficient of a reverse-symmetric mode in the resonance area especially.
