动力子结构实验技术融合数值计算和物理试验的优点，为工程结构试验研究提供了新的试验手段。振动台子结构实验技术能对结构整体动力特性进行全面模拟，是子结构实验技术发展的重要方面。试件与振动台耦合效应限制了振动台子结构实验技术对高频特性、非线性特性、大尺寸试件的模拟能力。目前只能进行质量远远小于台面的低频率物理子结构试验,无法满足超高层、大跨度、多介质耦合的工程结构抗震研究需求。本课题以大尺寸试件振动台动力子结构实验为研究对象，建立振动台子结构系统全过程模型，基于系统控制理论分析试件与台面耦合效应对振动台动力子结构实验稳定性和精度的影响，结合实时仿真与自适应控制理论建立两阶段控制策略，全过程补偿试件与台面耦合效应，以增强振动台动力子结构试验稳定性和精度，提高振动台子结构实验应用范围，并通过土结相互作用试验验证其有效性。本课题将为大尺寸试件高阶及非线性特性模拟提供新的试验手段，具有很好的应用前景。

Real time dynamic sub-structuring (RTDS) testing combines the advantages of numerical simulations and physical tests, which supplies a new method for the experimental investigation for structure dynamic performance. Shaking table RTDS is a key branch of RTDS because of its potential for testing the integral dynamic behaviour of structure. However, because of the coupling effect between structure and table, the testing capability of shaking table RTDS for high frequency and nonlinear behaviour of large scale specimen is limited. Thus, shaking table RTDS can only test the structure with a mass much less than table. This cannot satisfy the needs of the research on earthquake-resistance of super-high rise and long-span structure and the multi medium coupling in engineering structure. This research focus on the shaking table RTDS taking the upper part as physical structure. Firstly, the numerical model to describe the whole process of shaking table RTDS is planned to build. And then the effect of STI on the stability and accuracy shaking table RTDS is intended to analyse scientifically using control theory. After that, a dual function control strategy will be developed combining real-time simulation technique and adaptive control algorithm to compensate the coupling effect between structure and table, therefore the stability and accuracy of shaking table RTDS can be enhanced, so that the application of shaking table RTDS may be enlarged. Finally, the efficiency of shaking table will be validated in the application of SSI simulation. This research will make it possible to test large specimen with high order and nonlinear behaviour using shaking table RTDS and therefore has a good prospect of application.
