As an overall structural control system, earthquake resilient structure systems have different categories, including self-centering structures, rocking structures, and replaceable energy dissipating elements as structural fuses. This paper will give a review of the state-of-the-art and the state-of-the-applications of self-centering structures, rocking structures as well as multiform structural fuses. The overview shows that the recent development of earthquake resilient structure systems could be summarized as the following points, viz, the generalization of design ideas, complication of structural forms, diversified control thought, globalized research objects and universal application. It is pointed out that the main trend of the earthquake resilient
