Abstract: An equivalent calculation method for structural vibration control of a transforming TLD-structure to TMD-structure system is presented and proposed due to the easy implementation of TMD by numerical simulation. The derivation process of the transformation is reasonable and has explicit physical meaning. The analysis of a high-rise building structure 250m in height shows that the proposed method is feasible, accurate and can be directly used in the numerical analysis of the TLD-structure system by adopting commercial finite element software.
