- Abstract:
- A genetic algorithm based control design is proposed to control wind-induced vibration of long-spanroof in this study, An active tuned mass damper ( A’TMD ) controller is designed using the proposed methodolo-gy. Wind-induced control theory is presented firstly, The root mean square of displacement and aecelerationresponses are used as the evaluation criteria of control eliciency. Then procedures for control of wind-inducedvibration of long-span roofs based on genetic algorithms are given, Finally the method is applied to the controlof wind-induced responses of a long-span roof, The root mean square of displacement and acceleration respon.ses is caleulated for some typical measuring points, And the results are compared with those obtained from oth.er controller, The overall results of GA-based controller are accurate and efficient, The root mean square val.ues of displacement and acceleration of the sample points are reduced by 53.8% and 44.6% on average, re.spectively. GA-based controller reduces peak vertical displacement and acceleration of all sample points by65.7% and 56, 296 on average, respectively. GA-based control design methodology can obviously reducewind-induced vibration of long-span roofs, As an accurate and effective tool in wind-induced vibration control.the proposed method can provides some references for praetical projects.
