摘　　要：实时耦联动力试验是将物理试验与数值计算实时耦联的一种结构动力试验方法。这一试验方法兼具了常规振动台试验与拟动力试验的优点,被认为是结构动力试验方法发展的趋势之一,成为当前结构抗震试验研究的热点。该文首先阐述了实时耦联动力试验方法的基本原理以及关键问题,并综述了实时耦联动力试验研究的发展现状;然后介绍了清华大学水工振动研究组在实时耦联试验方面的研究实践;最后提出了实时耦联动力试验亟待突破的研究问题。Real-time dynamic hybrid testing （RTDHT） is an emerging method for simulating the dynamic response of structures under earthquakes, where an emulated system is divided into experimental substructure to be physically tested and the numerical substructure to be numerically analyzed. The method simultaneously processes the advantages of the shaking table testing and the pseudo-dynamic testing and thus is considered as a promising procedure for testing the dynamic behavior of complicated structures. This paper first describes the basic concept of the RTDHT and reviews the state-of-the-art research on the RTDHT. The investigations of the RTDHT carried out by the research group at Tsinghua University are then briefly introduced. Finally, some problems challenging the development the RTDHT are suggested.
