This note has presented approximate formulas for the design of a TMD system. For most buildings, the accuracy obtained from the closed form expressions is adequate for preliminary design. This note has also shown, using results of the feasibility study of the Citicorp Center TMD, that the effective damping of a building with a TMD is smaller than predicted by a model that represents the building by its first mode only.
