Other AbstractDuring the design phase of a giant sculpture, which is assumed to stand as a landmark, it turns out that its top tip displacements under wind loads are crucial design criteria, dominating the landscape views and the structural responses. This sculpture is not a single structure, instead, it's composed of eleven separated but closely arranged parts, which would exert significant influence on each other in the wind flow. So this article has developed a technology based on the concept of fluid-structure interaction, to evaluate the behavior of the sculpture under wind loads, to ensure both its scenery and structural performances. Firstly the coupled approach has been utilized to a single structure for validation. The numerical results of the maximum displacement of the top tip nodes agree well with the results from empirical estimation formula. Then fluid-solid coupling analysis on the real structure, and the displacement response characteristics of the top nodes under different strong wind conditions are obtained. Finally the safety of the structure under different wind conditions has been assessed, and the applicability of this sculpture in real conditions has been assured.
