摘　　要：建筑结构是由不同力学单元组合形成的复杂系统,从系统层次控制结构在强震下的动力响应与损伤过程对结构抗震设计具有重要意义。为使建筑结构具有“稳定、有序、渐进、可控”的地震损伤机制与破坏模式,预先设计明确的损伤机制和提高结构整体屈服后刚度是有效途径。在此背景下,“体系能力设计法”得以提出和发展。体系能力设计法通过在体系层次设置主、次结构,使结构的弹塑性动力响应受控于抗震能力较高的主结构,从而实现性态控制。该文综述了体系能力设计法中的关键科学问题在近年来的重要发展,并探讨了体系能力设计法的工程指导意义与未来发展方向。Building structures are complex systems consisting of different structural members. It is of great significance to the seismic design of structures to control the dynamic response and failure process under strong earthquakes at the system level. To ensure that the building structures show "stable, orderly, gradual, and controllable" seismic failure mechanisms and modes, one effective way is to pre-design a clear damage mechanism and improve the overall post-yield stiffness of the structure. To this end, the "system capacity design method" was proposed and developed. The method sets the primary and secondary structures at the system level so that the inelastic dynamic response of the structure is controlled by the primary structure with higher seismic capacity, thereby realizing the control of the seismic performance. This paper summarizes recent important research progress of key scientific issues in the system capacity design method, and discusses its engineering significance and future development.
