DEVELOPMENT OF SEISMICALLY ENGINEERED SUSPENDED CEILING OF LARGE SPACE STRUCTURES SUBJECTED TO EARTHQUAKE EXCITATION

Abstract

The failure of the large suspended ceiling systems has been one of the most widely reported types of nonstructural damage in building structures in past earthquakes. The results of shaking tests at some input levels showed the dynamic characteristics of the suspended ceilings and some ceiling specimens were damaged in a form which will lead to a successive collapse of a large suspended ceiling. This paper discusses an effective method of the clip connections which are developed to reduce the likelihood of the ceiling failure.
