Time history response of a tall building with a tuned mass damper under wind force
Abstract Tall buildings and observation towers are occasionally vibrated under strong winds and become uncomfortable for occupants. Therefore, various types of dampers are being developed at present to reduce the vibration in those structures. However, there is no sure way to predict the wind-induced response of a structure with a damper system and to estimate the suppressing effects of dampers under wind loadings. Therefore, authors have tried to simulate a time history wind force, which was not really in the last, to predict the response of a building with a tuned mass damper (TMD), and to discuss the suppressing effect of dampers under wind force. In this paper, it is shown that the simulation of wind loadings in time history is developed practically from the frequency-domain datas of wind, and a computatinal method of response prediction is presented for the structure with the TMD. Using that method, the behaviors of the TMD with various mass ratios and the suppressible quantities can be easily estimated.
