中文摘要：
为了克服地震模拟振动台对试验结构尺寸和质量的限制，并降低试验费用，将子结构试验技术应用于振动台试验，并提出了新型的振动台子结构混合试验方法。介绍了振动台子结构试验的基本原理，分析了2种实时加载方式和加载的具体过程，探讨了振动台子结构试验数值积分算法的特点，并结合算例分析了数值积分算法的稳定性和试验的可行性。数值仿真结果表明：当数值积分步长足够小、试验控制系统的滞后不大时，振动台子结构试验的结果能够很好地与全结构试验的结果相吻合。
英文摘要：
In order to overcome the size and mass restrictions of the experimental structure and reduce experimental costs in shaking table test, substructure experimental technique was used in real time dyfiamic hybrid testing for shaking tables （RTDHTST）, and the new type of RTDHTST method was put forward. Furthermore, the basic principle of RTDHTST was introduced, and two real-time loading modes and specific loading process were analyzed. Meanwhile, the characteristics, stability and feasibility of numerical integration algorithm with an example were discussed. Numerical simulation results show that, when the numerical integration step size is small enough, and the experimental control system does not lag behind, the results of the RTDHTST agree well with the results of the whole structure test.
