A cantilever slab has a span of 2.40 m. It is 150 mm thick and has an effective depth d = 110 mm. It is reinforced with 16 mm rebars @ 150 mm o.c. If f'c = 27 MPa, fy = 276 MPa, what is the safe live load that the slab can carry? Use 2015 NSCP strength design. Unit weight of concrete for DL: 23.56 KN/cu m.

Design Problem 1 & 2 Determine the cracking moment for the prestressed beam section shown if f'c = 35 MPa. Use a modular rupture of fr Assume normal weight concrete. = 0.621√ f'c C = 100 mm b₁ = 350 mm D = 125 mm d = 440 mm h = 500mm b₂ = 200 mm Figure 1.0 Cc 60 mm C-150 mm h, 250 mm b₁ = 250 mm b. =350 mm Figure 2.0 d 630 mm h = 700mm Ce 70 mm
