This paper presents an emergent method of new types of passive control buildings. In the process, a hybrid approach of a Genetic Algorithm and a nonlinear response analysis code is used to emerge a candidate set of vibration control buildings. Then, a tree-based model is used to classify and analyze the candidate set. This method enables us to determine the number, type or properties of control devices, and the type, dimension or location of the other structural members. In our numerical example, a high-rise building, whose primary structure and secondary structure are connected by hysteresis type dampers, is adopted. The stiffness and mass distribution of the building, the type of control buildings, and the yielding force of dampers are determined simultaneously using our method.
