Abstract
Under strong wind environments, most buildings do not have safety problems. However, the acceleration response of buildings causing discomfort of tenants is of considerable concern. To alleviate such undesirable building motion under strong wind gusts different passive or active control systems have been proposed and investigated [e.g., Refs. 1–3, 8, 9, 11–16, 19, 24, 25, 27]. Recently, an exploratory study for the application of an active mass damper control system to tall buildings had been considered in Ref. [16], in which the coupled lateral-torsional motions of the wind-excited tall building was considered. The importance of the torsional motion has been substantiated experimentally in Ref. [7] and analytically, in Refs. [10, 15, 16, 21]. It is the purpose of this paper to investigate the effectiveness of an active tendon control system for tall buildings subjected to strong wind turbulences. A transfer matrix formulation recently proposed to analyze the stochastic response of tall buildings under earthquake and wind loads [15–17, 19–23] is used.
