Abstract: An experimental procedure is developed for the testing of full- or large-scale structures under simulated seismic deformations in a quasi-static fashion. The procedure, pseudo-dynamic testing, is based on active modal control theory. The pseudo-dynamic testing procedure is a simultaneous simulation and control process in which inertia and damping properties are simulated and stiffness properties are acquired from the structure. The procedure calculates a set of dynamic displacements based on active control theory, utilizing the simulated inertia and damping properties and acquired stiffness properties under a hypothetical ground motion, and simulates the response of the structure under seismic motion in a quasi-static fashion. A detailed implementation procedure is presented for structures that can be modeled as discrete mass systems. The application of the procedure is simulated on the 1/5-scale model of the U.S.-Japan seven-story reinforced concrete frame wall structure.
