ANALYSIS OF THE PRESENT SITUATION OF RESPONSE CONTROL SYSTEMS IN JAPAN BASED ON THE SURVEY OF APPLIED BUILDINGS(Structures)

Abstract

Twenty years have passed since response control systems, which reduce structural damages caused by earthquakes or strong winds, were used in actual buildings. JSCA conducted a survey of response controlled buildings on design offices and construction companies, and made a database. Based on the database, first, this paper classified the number of the buildings which use response control systems by construction years, purposes of the buildings and types of device mechanisms. And, this paper analyzed the distribution of the applied damping forces, and their response reduction efficiency. Finally, this paper reports the result of this analysis, and discusses the present situation of response control systems in Japan.
