Description
This paper presents a new structural control method for the combination between passive base isolation and active structural control based on the equivalent-input disturbance method (EID). Nowadays, many high rise buildings employ base-isolation systems. Passive base-isolation enlarges the natural period of a building. It results in the suppression of the absolute acceleration of buildings. However, it increases displacement of the base-isolation story and may force it beyond its allowable range. In this back ground, the combination between a passive base-isolation and an active structural control has been the focus of constant attention as of late. On the other hand, suppressing absolute acceleration and inter-story drift are most important to protect a building, property, and people from a large earthquake. However, most active-structural control do not consider these responses. In contrast, this study constructs a new active-structural-control system based on the EID method that considers absolute acceleration and inter-story drift.
