In this paper, the passive control approach to three dimensional building structures excited by 2-dimensional earthquake ground motions is presented by using Bi-direction tuned masse damper (TMD) system. The mathematic model of a multi-storey building structure including the TMD system is established and its combined equation of motion is given. The optimization of TMD parameters can be obtained by using the Genetic Algorithm Method based on the object function. The numerical example shows that the presented method is effective and flexible. It may obviously control the translational response and rotational response of three dimensional building structures.
