A 1.4 m wide x 0.33 m thick RC footing is to be provided for a 250mm thick RC wall. The wall carries a dead load of 170 kN/m and a live load of 338 kN/m of the wall. The gross allowable soil pressure is 330 kPa. The bottom of the footing is 625 mm below the ground. Use f'c = 21 MPa and fy = 420 MPa. Unit weight is 23.6 kN/m3 for concrete and 18.4 kN/m3 for the soil backfill. The diameter of main bars is 16mm and that of the shrinkage and temperature bars 10mm

Question
A 1.4 m wide x 0.33 m thick RC footing is to be provided for a 250mm thick
RC wall. The wall carries a dead load of 170 kN/m and a live load of 338 kN/m
of the wall. The gross allowable soil pressure is 330 kPa. The bottom of the
footing is 625 mm below the ground. Use fe = 21 MPa and fy = 420 MPa. Unit
weight is 23.6 kN/m3 for concrete and 18.4 kN/m3 for the soil backfill. The
diameter of main bars is 16mm and that of the shrinkage and temperature bars
10mm
Calculate the required spacing of the main bars in mm
Answer in four decimal places. (i.e. 230.2112, 102.3292)
DO NOT ROUND OFF FINAL ANSWER IN MULTIPLES OF 10mm
