A 395 mm thick slab supports a 363 mm thick wall carrying uniform service dead load of 211.5 kN/m and service live load of 157.4 kN/m. The base of the wall footing slab is 1.4 m from the ground surface. Design parameters are as follows: Ysoil = 16.5 kN/m, Yconcl = 24 kN/m°, qa = 207.92 kPa, f'.- 27 MPa and f, = 414 MPa. Calculate the required center to center spacing of 16 mm bars for flexure. Note: Present the width (B) in multiples of 100 mm and present the exact required spacing in 2 decimal places (do not round off).
