Is there any particular consideration on having an axially loaded steel column (compression and tension) placed directly over a deep footing (1.6 m deep)? without either a pedestal or pedestal rebar inside the footing (embedded pedestal)? Appart from punching shear, is there any other consideration to consider that are not on codes? Anchor bolts will end deep with an end plate (they are 2 inches diameter), so i don't need any rebar parallel to the anchor bolts. Also, I don't need to confine the concrete, since the base plate is generous, so no stirrups forming an embedded pedestal. So the footing will have just bending rebar (bottom and top). All my calculations are OK (pull out, punching shear, endplate thickness, etc.), it is just I haven't seen similar things with big axial loads. Any comments?
