Square Footing Design A square column footing is to support a 500-mm square tied column that carries service dead load of 800 kN and service live load of 1000 KN. The column is reinforced with eight 25-mm-diameter bars. The base of the footing is 1.50 m below the natural grade where the allowable soil pressure is 310 kPa. The soil above the footing has unit weight of 15.6 kN/m³. Assume fy = 275 MPa, f = 27.5 MPa, and unit weight of concrete as 23.50 kN/m³. Design the footing. Use 25 mm main bars and 75 mm clear cover. Use NSCP 2015.

Square Footing Design
A square column footing is to support a 500-mm square tied column that carries
service dead load of 800 kN and service live load of 1000 KN. The column is reinforced
with eight 25-mm-diameter bars. The base of the footing is 1.50 m below the natural
grade where the allowable soil pressure is 310 kPa. The soil above the footing has unit
weight of 15.6 kN/m³. Assume fy = 275 MPa, f = 27.5 MPa, and unit weight of concrete
as 23.50 kN/m³. Design the footing. Use 25 mm main bars and 75 mm clear cover. Use
NSCP 2015.
