iii) QUESTION FOUR The given figure 2 is the first floor plan of an office building. It is estimated that the live load on the floor slab is 4.0kN/m² and the load due to floor finishes and ceiling below it grade 30 and high yield steel reinforcement, answer the following questions; is 0.5kN/m2. This building requires a fire resistance of one hour. By using concrete of 6@ 4 m i) If the modification factor for tension reinforcement is 1.2, the effective depth, d is..... a) 118 mm 128 mm 138 mm 148 mm ii) The nominal cover for the slab is... a) 20 mm 25 mm 30 mm 35 mm b) c) b) c) d) b) d) c) The self-weight of the slab is... a) A: 3.96 kN/m² b) B: 4.96 kN/m² c) C: 5.96 kN/m² d) D: 6.96 kN/m² Figure 2 iv) By using h = 165 mm.
