In this paper, the distribution characteristics of the earthquake forces in the core wall and outer frame are centered around, which are two earthquake fortification lines in this structure system. The commonly used methods are summarized, which are adopted to intensify the first fortification line—the ductility of the core wall and to increase the second fortification line —the stiffness and ductility of the outer frame, and their advantages and disadvantages are analyzed respectively. 收起
