If standard is required use AS3600

Question 1 (35 Marks) Beam and Slab Design i. Figure 1 shows a serious continuous beam that is monolithically cast with a 125mm deep R.C slab. The slab carries a superimposed dead load of 1.2kPa and live load of 4.2kPa. Determine the factored distributed loading (w), consisting of all the dead and live loads, carried by the beam. Assume the beams are spaced at 4.4m (centre to centre). Use a RC weight of 24.5kN/m. ii. iii. iv. V. vi. vii. (4 Marks) Use the code defined approximate method of analysis to determine the bending moments and shear forces for which the beam shown in Figure 1 should be designed. (6 Marks) Design the bending reinforcement for this beam over the centre support, using only N20 reinforcement. Sketch the reinforcement layout at this section. (6 Marks) Calculate Vuc. Vu min. and Vax for the beam and use this information to comment in general terms on the shear reinforcement requirements for the beam. (4 Marks) Design the shear reinforcement needed at the point of maximum shear. (5 Marks) Roughly sketch the detailing of reinforcement for this continuous beam indicating the reinforcement designed above for flexure and shear. (6 Marks) Determine the maximum total and incremental deflections. Assume that y, = 0.7 and = 0.4. If the total and incremental deflections are limited to span/250 and span/500 respectively, check whether this requirement is satisfied.
