Abstract

Abstract: This discussion is based on the paper by Farshidianfar and Soheili[1] . In this paper, the authors consider Soil–Structure Interaction effects (SSI) and optimize parameters of Tuned Mass Dampers (TMD) to decrease the earthquake vibrations of tall buildings. They also develop a mathematical model based on the time domain analysis. In this discussion we show that the offered model is not accurate enough and we rectify the model. Highlights: A mathematical model is developed for a structure with TMD and SSI effects. Lagrange method is used for deriving governing equations of motion. The state space method is employed to solve the equations in time domain.
