Abstract

Abstract

In order to obtain the optimal parameters of TMD devices for a building structure subjected to TMD random wind loads and based on comfort and power reliability, the analytical solution for the acceleration of windinduced response associated with the comfort of the structure of the first-order mode was got. Then, according to extreme value theory of random process, the average maximum wind-induced displacement of the structure was got. And the ratio of the standard deviation of the first-order modal displacement of the structure with TMD dampers to that without TMD dampers was defined as the index of damping effect and it was used as the optimal objective, which had degrees of comfort and dynamic reliability for the restrictive conditions. Finally, the optimal parameters of TMD dampers are got by the improved genetic algorithm . Therefore, a series of methods for the optimum design of TMD dampers structure based on the constraint of comfort and dynamic reliability were established. Studies show that the method can effectively obtain the optimum parameters of TMD devices.
- TMD dampers,
- win-induced random response,
- improved genetic algorithm,
