Problem#1 Design a reinforced concrete rectangular column and its spread footing, if the architectural design requires that its width must be 250 mm. The column supports dead and live loads of 500 kN and 750 kN respectively, and the allowable net soil pressure is 200 kN/m. Use 650 mm thickness for the footing. Hint. Initially assume the percentage of reinforcement as 2% for the column. Design data Column Footing fc' = 30 MPa fc = 25 MPa do = 25 mm d) = 20 mm Cover = 50 mm Cover = 75 mm fy = 420 MPa Yconc = 24 kN/m3 Problem#2 (Homework): Design a reinforced concrete rectangular column and its spread footing, if the architectural design requires that its width must be 300 mm width. The column supports dead and live loads of 600 kN and 800 kN respectively, and the allowable net soil pressure is 220 kN/m. Use 700 mm thickness for the footing. Hint. Initially assume the percentage of reinforcement as 2.5% for the column. Design data Column Footing f! = 25 MPa f' = 20 MPa do = 20 mm dp = 16 mm Cover = 50 mm Cover = 75 mm fy = 420 MPa Yconc = 24 kN/m
