Abstract

Wind response control of tall buildings on flexible foundation using multiple tuned mass dampers (MTMDs) is studied. The MTMDs are installed at the top of the reinforced concrete (RC) buildings duly considering soil-structure interaction (SSI). The rigid circular foundation and the surrounding soil are modeled by considering frequency independent constants for the springs and dashpots. The time domain wind analysis based on Newmark’s method of average acceleration is employed for the non-classically damped system. The performance of the MTMDs is compared with the case of single tuned mass damper (STMD). The displacement and acceleration response at the top of the building under the along-wind and across-wind forces are computed to study the effectiveness in installing the STMD and MTMDs. It is concluded that the soil type does affect the design parameters of the STMD and MTMDs, and wind response of the building on the flexible foundation. Furthermore, the MTMDs are found to be more effective than the STMD.
