A reinforcement member is provided for an extendible scissors truss such as may be utilized in a collapsible canopy structure wherein the extendible scissors truss has members pivotally connected to form truss cells. The reinforcement member has first and second end portions joined by a linking portion to form a Z-like configuration. The first and second end portions of the reinforcement member are each attached, at an end point, to one of a pair of parallel members of a cell, and lie laterally adjacent the truss members when the extendible scissors truss is in an extended position. The cell is thereby reinforced against moments resulting from side forces applied to the truss by torsion and bending stress developed in the linking portion of the reinforcement member.
