Question 4 (25 marks) A ribbed slab is continuous over four equal spans of Lm each (Figure 4). The dead loading including self-weight, finishes, partitions etc. is p kN/m²and the imposed load is a kN/m2. The construction materials are grade 35 concrete and grade 500 reinforcement. Design the end span of the slab. Cover is assumed to be 25 mm and preferable size of reinforcement is 12 mm. a (a) S s 100 250 Effective depth 125 b (b) Figure 4 (a) Ribbed Slab; (b) Cross-section a) Determine the value of effective depth. b) Calculate the moment and shear in the rib. c) Design mid-span and support moment reinforcement d) Check for shear for the rib slab. e) Check for deflection for the rib slab. f) Propose reinforcement for the topping.
