Figure 1 shown below delineates a reinforced concrete floor, which has a characteristics strength, f, of 32MPa. Determine design moments in support and on mid span in kN.m (per m width) for slab S3. The design information of the slab S3 is as follows: Design Information: • Thickness of slab (D) is 180mm • Live load factors for long term (₁) and short term (s) are 0.4 and 0.7 respectively • Column cross section = 300mm X 300mm • All the beams are 350 mm in depth and 300mm in width. • Live load, Q=1.5 kPa • Width of slab, b = 1000mm • Adopt N12 bars as reinforcement (short and long span) with clear cover of 25mm • Density of concrete (p) is 2400kg/m³ • Specific weight of concrete (y) is 24.6 kN/m³. • Yield strength of steel reinforcement (fsy) =500 MPa 3 m 3 m 7m S1 S2 S2 S1 7m S4 2 m 7 m S3 S5 5 m O 6 m 6 m Figure 1 shown below delineates a reinforced concrete floor, which has a characteristics strength, f, of 32MPa.
