As a result of the sudden change of lateral stiffness of substructure and superstructure, the earthquake reaction abruptly changes correspondingly, which bring about great difficulties and deviation to research and application. The paper first expounds the bad influences of high transfer story. Then, the author raises the concept of' double control' with the ratio of lateral stiffness and story drift to eliminate disadvantages using one target. Combined with practical project, parameters of' double control' are presented at the same time, which can be referred in the theoretic investigation and design of engineering.
Keywords: high-rise building; high transfer story; the ratio; equivalent lateral stiffness; story drift; concept of double control, target parameter
