A real-time hybrid testing system including additional translational and rotational degrees of freedom was developed based on the existing real-time hybrid experimental technique in which shake table testing of structural components and numerical computation of structural systems are performed synchronously in real time. Dynamic actuators, moment-torque loading devices and shake tables are considered as the loading equipments, feasibility of the proposed type of the test is analytically investigated. Fundamental properties of the test system is discussed based on the stability analysis using state space representation of the dynamics of the test system including the phase delay in the loading, model mass, natural periods, and damping assumptions. Moreover, numerical simulation of the real-time hybrid test using a shake table including translational and rotational degrees of freedom is conducted in order to clarify the accuracy and reliability of the test result depending on the structural and system dynamic properties. Actual test system was developed using DSP-based controller, and hypothetical test result indicated the feasibility of the test, and application of adoptive control strategy is shown to be a promising approach. Finally, a series of real-time hybrid loading tests using moment feedback signal with a model of an inverted pendulum was successfully conducted.
