Design of TMD for damped linear structures using the dual criterion of equivalent linearization method
Design of tuned mass damper (TMD) for damped linear structures has attracted considerable attention in
recent years. Some approximate expressions of optimal tuning ratio of a TMD attached to a damped
linear structure have been proposed. In the paper, another closed-form expression for the optimum
tuning ratio is presented for two models, excitation force and ground motion. This approximate
analytical solution is obtained by using improved equivalent linearization method according to dual
criterion. The values of optimum tuning ratio derived from the expression proposed in the present study
have been compared with those obtained numerically and from results investigated by other authors.
The comparisons have verified the accuracy of the suggested expression for both small and large
structural damping
