摘　　要：结合基于性能抗震设计概念,介绍了体系能力设计法在消能减震结构中的应用。依据体系能力设计法建议了消能减震结构抗震设防目标,并通过算例分析给出了满足体系能力设计方法所需具备的条件。在此基础上,给出了消能减震结构设计中阻尼器分布、阻尼器参数和等效阻尼比等有关计算方法。According to performance based seismic design concept, the application of structure system capacity design approach （SSCD） proposed by the first author in energy dissipation structures is presented. Based on SSCD approach, the seismic performance goal is recommended and the design requirements of the energy dissipation structures are proposed with the parameter study. Based on these researches, the calculation methods of the parameters and distribution of energy dissipation devices and equivalent damping ratio are proposed.
