<p>This Architectural drawing is Foundation Steel Plate Detailing. Base plates <strong>usually are attached to the column during the fabrication of the structural steel and delivered as one piece</strong>. When the columns and/or base plates are very heavy, it. <strong>Loads from steel columns are transferred through a steel base plate to large area of the footing</strong> . The base plate can be welded directly to the columns ,or they can be fastened by means of some type of bolted or welded lug angles . The base plate acts as <strong>an interface between the superstructure and the foundation</strong>; thus, completing the load path into the foundation. Base plates help provide a uniform distribution of superstructure loads to the foundation, and therefore conform to the shape of the foundation, typically a square or a rectangle.
