【Abstract】 A principle and optimization method of multifunctional vibration-absorption megaframe structures is presented. By changing the tuned ratio and the damping ratio, the effectiveness of multifunctional vibration-absorption megaframe structures under earthquake and wind excitation is discussed in both time and frequency domains. The results show that the response of multifunctional vibration-absorption megaframe structures under earthquake and wind excitation is much less than that of normal megaframe structures.更多还原
