Control of Tall Buildings in Along‐Wind Motion

Abstract

An exploratory study is made of the possible application of active control systems to tall buildings in along‐wind motion. An analytical procedure is developed to compute the statistical properties of the structural response of a tall building implemented by an active control system and excited by a random wind flow which is stationary in time and nonhomogeneous in space. The problem is formulated in terms of transfer matrices and the random vibration analysis has been carried out. A numerical example of a 40‐story building is given to illustrate the significant reduction of the acceleration response using either an active mass damper or an active tendon control system.
