Abstract

Abstract

Mega-sub controlled structure(MSCS),an isolated substructure used in mega-frame building,has attracted more and more attention of designers for its prominent controlling effectiveness in mega-frame building.An active control,for mega-sub controlled structure subjected to random along-wind loads is investigated based on LQR algorithm.Dynamic equation and method for assembling parameter matrixes for the mega-sub controlled structure under random wind loads are presented.A change in control parameter and time lag that influences the response controlling effectiveness,control force and dynamic characteristic of the MSCS under active control are discussed.The result indicates that the new structure employing active control can offer an effective means of controlling and the controlling responses of this building are sensitive to weight matrix.The controlling effectiveness under active control will be decreased when time lag is considered.
