Abstract: A building assembly for forming a frame of a building including at least two elongated column structures and a truss structure supported on the column structures. The truss structure has opposite end portions resting on the column structures at horizontally spaced locations. A trilateral bracing structure may be attached to the truss structure and one of the column structures to tie the truss structure to the column structure. The trilateral bracing structure may be separable from the truss structure and the column structure.

Abstract: A cart loading system for loading materials on a cart in a orderly and compact manner even if the materials being loaded have different dimensions. The cart loading system includes a frame for positioning on a floor surface adjacent to a material shaping table, and at least one material support arm assembly for moving a piece of material from the material shaping table to a position over the frame. A carriage assembly is provided for moving a material cart in a first direction and a second direction with respect to the frame, and includes a subframe movable in the second direction on the frame and a shuttle mounted movable in the first direction with respect to the subframe. A first moving assembly is provided for moving the shuttle in the first direction on the subframe, and a second moving assembly is provided for moving the carriage assembly in the second direction on the frame. A detection assembly detects movement of material on the support arm assembly and generates a detection signal.
