[Abstract]:The optimal design of wind vibration control of towering structures is studied. Firstly, according to the characteristics of the towering structure and the annular tuned liquid damper (Tuned Liquid damper), the dynamic model of the annular TLD control of the towering structure is established. Then, based on the multi-objective genetic algorithm (NSGA-II (Nondominated Sorting Genetic Algorithm 鈪，
