MECHANICAL PROPERTIES OF STEEL FURRING SUSPENDED CEILING SYSTEM UNDER STATIC IN-PLANE COMPRESSION

Abstract

In recent years, suspended ceilings were often damaged by earthquakes. Investigations on seismic capacity of ceilings have been conducted by some researchers. The new standard for ceilings against earthquakes requires a relatively large clearance around those to prevent collision with surrounding walls. On the other hand, there are still the needs for ceilings without clearance because of workability or room’s uses. In this paper, mechanical properties of steel furring suspended ceiling system for in-plane compression are clarified by static compression tests, using small and large scale specimen. Those properties are essential to evaluate the seismic capacity of ceilings without clearance.
