THE SPACIAL DYNAMIC RESPONSES OF WIND LOAD AND OPTIMAL CONTROL FOR TALL TVTOWER STRUCTURES

A kind of semi-active manipulable TMD system was proposed in this paper according to characteristic of TV-tower in shape of revolutionary shell. A computer software was worked out with the theory of revolutionary shell. On this basis, the optimal calculation for location, quantity and parameters of TMD system was introduced. The results of optimal calculation show that the manipulable TMD system has obvious vibration absorption effects.
