中文摘要：

作为一种新兴的抗震研究方法，混合模拟试验将数值分析与物理试验结合，突破了结构的尺寸限制，降低了试验费用，因此在相关研究领域得到了普遍关注，并在美国地震工程模拟（NEES）研究项目中得到广泛的应用。基于NEES项目总结了混合模拟试验在美国地震工程中的应用，首先介绍了混合模拟试验的基本原理和积分算法，然后在结构性能研究和试验方法研究两方面进行了详细讨论。通过总结归纳，指出了今后有待研究的问题。

英文摘要：

Hybrid simulation, as a burgeoning seismic experimental method, combines numerical simulation and physical experiment. 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.
