Vertically distributed multiple tuned mass dampers in tall buildings: performance analysis and preliminary design
10.1002/tal.499.abs
This paper investigates the structural performance of vertically distributed multiple tuned mass dampers (MTMDs), which can save valuable occupiable space near the top of tall buildings, control the first as well as higher mode responses and be installed more easily because of smaller tuned mass damper (TMD) masses. Vertically distributed MTMD theory is presented. With this theory, the effectiveness of vertically distributed MTMDs along the building height is predicted using simplified models, compared with the conventional TMDs installed near the top of tall buildings. Vertically distributed MTMDs are designed for a typical 60‐storey tall building subjected to representative dynamic wind loads, and their performance is measured. The results of these studies show that TMDs can be distributed vertically along the building height without substantial loss of their effectiveness. Considering their advantages over the conventional system, vertically distributed MTMDs possess a high potential of practical applications for tall‐building motion control.
