Abstract

AbstractA number of active control systems have been developed, fabricated and installed in full‐scale structures and they have been subjected to actual wind forces and ground motions. The focus of this paper is on the observed response of several of these systems. They include an active bracing system and an active mass damper system installed in a six‐story experimental building, and two hybrid mass damper systems installed in two actual buildings. The configurations of these systems are summarized together with their performance characteristics. Observed performance of these systems during actual wind storms and moderate earthquakes shows that they meet their basic design objectives. Furthermore, their performance can be adequately predicted through simplified analytical and simulation procedures.
