About this detail

An interior gravity column base plate is supported by a concrete pedestal and dropped footing. The column sits on a base plate anchored to the concrete pedestal, with top of slab, pedestal, and footing elevations sized per plan. The pedestal is reinforced with number four ties spaced at two inches on center near the top and twelve inches on center for the remainder, alongside number four dowels at each anchor. A two-inch concrete clearance is maintained at the top faces, with three-inch clearance typical for the footing. Additional dowels at each face are sized per the pedestal schedule, and number four bars are placed at each side with standard hooks at each end. A note specifies that this anchorage detail applies to non-batter-frame columns only, directing users to sheet S-5521 for batter-frame anchorage details.
