Question 2:

 

Figure 2 shows the beams layout of a reinforced concrete building. The concrete compressive strength, f_{c} = 28MPa and the reinforcing steel yielding strength, f r =420MPa. Beam B2 has a rectangular cross section of width, b = 450mm and thickness, h = 450mm with effective depth, d = 390mm and Beam B1 has a rectangular cross section of width, b = 450mm and thickness, h = 1000mm with effective depth, d=900mm. 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 6.0kN / (m ^ 2) respectively in addition to its self-weight. The slab is reinforced with flexural bottom bars of Ø16/150mm. Check the slab to carry the applied loads.
