摘　　要：首先全面阐述了冗余度的概念以及9.11事件以来冗余度理论在建筑结构领域的发展现状;其次,论述了建筑抗震冗余度的含义及其必要性,并指出增加建筑抗震冗余度的两条途径:大幅度提高建筑抗震承载能力的安全储备和设置多层次的抗侧力体系;最后,对建筑抗震冗余度理论的研究现状、评价指标以及国内外抗震规范的相关规定进行了详尽的阐述。In this paper,the concept of redundancy and the development status of redundancy theory in the field of building structure since the September 11 Attacks are comprehensively expounded. Secondly,the meaning and necessity of the building aseismic redundancy are discussed,at the same time,the measures to increase the building aseismic redundancy is given,namely,to increase the building seismic capacity greatly and/or set up a multi-level lateral force resisting system. Finally,the research status of the theory of building aseismic redundancy,evaluation indexes for building aseismic redundancy and the relevant provisions of the domestic and international seismic code are described in detail.
