Question
Figure 1 shows the beams layout in one-way solid slab system in a reinforced concrete building. Each column has a square cross section of 800mm side length. The concrete compressive strength, f_{C} = 28MPa and the reinforcing steel yielding strength, f_{y} = 42OMP*a_{2} All beams have rectangular cross sections of width, b = 500mm and thickness, h = 700mm with effective depth, d=630mm. . The slab has a thickness, h = 250mm with effective depth, d=200mm. The slab is subjected to superimposed dead and live loads of (5, 0kN) * m ^ 2 and (6,0kk/m^ 2 respectively in addition to its self-weight. The perimeter walls are 10kN/m weight. Determine the required bottom bars in the interior span in beam B1. Use the ACI coefficients for analysis.
