| Abstract |
A smart tuned mass damper (STMD) was proposed in this study for the suppression of wind-induced motion of high-rise buildings. To investigate the effectiveness of a STMD for the response control of a wind-excited tall building, a benchmark building, that is a 76-story concrete office tower, was used. It is a slender building 306m tall with a height to width ratio of 7.3. An idealized variable damping device and a magnetorheological (MR) damper were used replacing a passive damper to improve the control effect of a conventional TMD. Skyhook control algorithm was used to appropriately modulate the control force of STMD. The control performance of STMD was evaluated comparing with the sample TMD, ATMD. The numerical studies show that the control effectiveness of STMD is significantly superior to that of the conventional passive TMD. It is also shown that a STMD can reduce the response similar to the ATMD; however, with an order of magnitude less power consumption. |
