Consider The One Way Slab With Overhang Shown In Fig 4 The Slab Supports The Superimposed Dead Load Does Not Include S 1 (155.37 KiB) Viewed 40 times

Consider the one-way slab with overhang shown in Fig. 4. The slab supports the superimposed dead load does not include self-weight) and live load shown in the figure. All the loads are specified (unfactored) and you are to consider 1.25D + 1.5L and a l m wide slab design strip: a) Draw the shear (V) and moment (M) diagrams (2 points) Note: Use the beam load table shown on the next page b) Check that the slab is thick enough to provide adequate shear resistance without stirrups (3 points) Note: Do not revise the design if it does not pass c) Using 15M bars, specify a spacing for the main tension steel in the positive moment region. Note: use z=0.9d, but then check Mr at the end. Make sure your design meets the Asmin and smax requirements in the CSA A23.3-19 standard. (5 points) d) Using 15M bars, specify a spacing for the main tension steel in the negative moment region. Note: use z=0.9d, but then check Mr at the end. Make sure your design meets the Asmin and smax requirements in the CSA A23.3-19 standard. (5 points) e) Using 15M bars, specify a spacing for the shrinkage steel. (3 points) f) Show a neat sketch of your slab design and reinforcement layout (2 points) Note: You don't need to design bar cutoffs but show approximately how the bars would be placed 9. = 2.5 kPa (superimposed dead load, does not include self-weight) 9 = 3.6 kPa (live load) 1 h = 310 mm B 1 m slab strip 6600 mm 1600 mm A = pin B = roller f'c = 30 MPa Fy = 400 MPa Max aggregate = 20 mm Clear cover = 20 mm 15M bars (no stirrups) Note: w (in KN/m) = qx1m W Figure 4
