Abstract: Wind response control of a 76-storey benchmark building installed with distributed multiple tuned mass dampers (MTMDs) is investigated. The performance of the distributed MTMDs is compared with all MTMDs placed at top floor and with single tuned mass damper (STMD) having same total mass. The STMD is placed at top floor of the benchmark building; different mass ratios are given for STMD to improve performance of the building. The MTMDs are placed at top floor of the benchmark building; same way different mass ratios are given to MTMDs to improve performance of the building. The TMDs are placed where the mode shape amplitude of the buildings is the largest/large in the particular mode and each tuned with the corresponding modal frequency, while controlling first five modes in MTMDs. The mass ratios are varied to obtain improved performance of the building. It is concluded that MTMDs are more effective than the case of STMD, and further, the distributed MTMDs are more effective to control wind induced vibration of the building.
