Abstract
In a suspended ceiling for earthquake prone locations, a line of seismic main beam connections of the invention between main beams separates the ceiling into segments that move independently of each other during a quake, to limit a build-up in ceiling momentum. A slotted fishplate in the connection is set to keep the beam ends stable about a gap before a quake, and slidably connected about the gap during a quake.
