It overcomes size restriction of specimens and reduces cost , getting wide attention around the world. Hybrid simulation has been applied in Network for Earthquake Engineering Simulation ( NEES) projects. This paper provides an overview of hybrid simulation applied in these projects based on information available on the NEES warehouse. First , this paper introduces hybrid simulation method and integration algorithm. Secondly , the hybrid simulation applications in earthquake engineering across NEES projects are discussed , considering application on investigating structural performance , and development of hybrid simulation methods. This paper summarizes application of hybrid simulation and points out some issues in further research.
