Paper Abstract

This paper describes experimental work on the semi-active control of structural modal energy by dynamically controlling structural stiffness. Stiffness adjustment of the structure is achieved by engaging or disengaging `relaxed' control elements, thus changing local stiffness and changing the global eigenstructure without the introduction of energy into the system. Experiments on a three story laboratory model are described. Control experiments when the model is subjected to sinusoidal and random excitations demonstrate feasibility.
