Earthquake Responses of Steel Frame Structures having a Structural Control System using Non-Structural Members

Abstract

Many structural control systems have been demonstrated to reduce the response during an earthquake and have gradually been applied to buildings. However, almost all the systems have required closure of the inter-column opening in order to install the damping devices. The authors have proposed a structural control system using non-structural members for steel buildings. This system is composed of non-structural members, which are short span beams. These members as hysteretis dampers absorb vibrational energy by their hysteretic damping performance. In this paper, the earthquake response analysis of the steel building has been carried out in order to under stand the behavior of the proposed system. As the result, the usefulness of the system has been discussed.
