Recent advances in structural control

This article updates a previous one that appeared in the October 1985 issue of The Shock and Vibration Digest. Interest in structural control has been growing with the emphasis now placed on experimental programs that will substantiate the various theories and designs that are currently proposed. The key idea behind structural control is to keep the response of a structure within certain bounds dictated by serviceability. This can be achieved by passive control, active control, or a combination of these two basic approaches.
