An expansion joint assembly for use between elongated, adjacent, relatively shiftable, joint-defining structural sections (e.g., floor sections) is provided which exhibits three degrees of freedom for accommodating essentially all relative movement of structural members. The preferred assembly is fire-rated and includes a pair of elongated metallic supports adapted for fixed attachment to a corresponding structural section adjacent an expansion joint, together with an elongated, flexible, U-shaped bridging member. Connection between the bridging member and the supports is provided by means of interfitted, longitudinally shiftable U-shaped elements respectively secured to the supports and the adjacent edges of the bridging member. The metallic supports preferably include abutment structure overlying a corresponding interfitted pair of connection elements, in order to maintain the elements in their proper orientation, even in the event of vertical shifting of the structural sections.
