Unlike the frame of the Hanover National Bank Building, which had been constructed from many built up columns and beams, the main structural members of the new annex are largely single, hot-rolled sections. In the first decades of the 20th century steel manufacturers competed to roll ever larger steel members. Despite the number of larger sections available, many members were still built up from angles and plates. Here cover plates are visible on the columns below grade. Splice plates are visible at the top of the columns in the foreground, as are connection plates on the inner and outer faces of the column flange for bracing. The bracket on the outer flange of the column will support a beam at the ground floor level. Most beam to column connections are placed at the flange or web of the column to minimize eccentricity. The beam at the ground floor may have been located outside the column line to allow support of the exterior masonry cladding.
