A real-time structural parameter modification, approach for random vibration reduction: part II. Experimental verification

摘要

Earthquake induced structural vibrations are stochastic in nature. In this paper, we present a novel structural control methodology for earthquake vibration reductions in two parts. Part I summarizes the efforts of the authors toward the development of real-time structural parameter modification(RSPM) control between 1993 and 1996. The operating control principle is minimization of conservative energy. The control hierarchy is realized by low-power-consuming devices (functional switches) with multiple ranked loops. The control method is to optimally adjust the physical parameters (mass, damping and stiffness) of the structure in real time.
