Problem No. 1 The entrance canopy of a building, 2.50m x 6m in dimension, is to be design as a slab. It will carry the following loads: a uniform live load of 2000 Pa, a uniform dead load of 5000 Pa (excluding the slab weight) and a concentrated dead load of 5000 N, per meter of the slab, applied at the extreme end of the support. Design the canopy if one of its longer sides is fixed to the wall and serves as its support. Use the following design properties: f 'c = 21 MPa, fy = 345 MPa, 16-mm-diameter main bars, 10-mm-diameter temperature bars and 20 mm clear cover. Positive Moments: 1. End Spans a. If discontinuous end is unrestrained b. If discontinuous end is integral with the support 2. Interior Spans wL2 /11 ---- wL2 /14 wL2 /16 ... Negative moments: 1. Negative moments at exterior face of first interior support: a. Two spans b. More than two spans wL? /11 wL2/10 2. Negative moment at other faces of interior supports- 3. Negative moments at face of all supports for a. Slabs with spans less than 3m --------- wL? /11 wL? /12
