ACI 18

Figure 1 below shows the plan of a reinforced concrete solid slab with perimeter (exterior) beams only. The columns have a square cross section of 500mm side length. The beams have width, bw= 500mm and a thickness, h=800mm. The slab thickness, h=280mm with effective depth, d=230mm. The Concrete compressive strength, fc=28MPa and steel yield strength, fy=420MPa. Superimposed dead load on the slab, WsD= 4kN/m2 and live load on the slab, Wu=5.0kN/m2. Determine the spacing of 14mm bottom bars in x and y directions in the hatched panel.
