In this paper,the core idea behind seismic performance-based design is first introduced. Based on a seismic damage survey of retaining walls,the research necessities of seismic perform-ance-based design for gravity retaining walls in high seismic intensity areas are explained.For es-tablishing a framework for seismic performance-based design methods,key technical problems of current specifications and seismic performance-based design methods are summarized.According to large-scale shaking table tests of retaining walls,conclusions about which displacement index can be used as a measure of the seismic performance of retaining walls are presented,along with the criteria and flows of seismic performance-based design methods.Through comparisons be-tween seismic performance-based design methods and specifications of retaining wall examples, the advantages of seismic performance-based design methods are demonstrated.Finally,engineer-ing application suggestions for seismic performance-based design of gravity retaining walls in high seismic intensity areas are proposed.
