Response of discussion “Estimating optimum parameters of tuned mass dampers using harmony search”

In the discussion of Saberi et al., the optimum TMD parameters obtained by using Harmony Search (HS) algorithm were investigated for two different method. These methods are mode superposition method and expressing governing equations in state space format. In original paper, modal superposition method was used as defined. In this response, the optimization process was repeated for the same numerical examples by directly solving coupled equations of motion.
