Reinforced concrete  density is 24 kN/m3.  Note the following specified conditions of service. Location:   Cairns, QLD (more than 50 km from coastline)  Construction:   Standard formwork and compaction   Figure 1. Two-way RC Slab Design   Answer the following questions using the simplified method in AS3600.  (i) Determine the appropriate reinforcement cover to satisfy durability and 120- minute fire resistance requirements.  (10 marks)  (ii) Determine the minimum slab thickness to satisfy total and incremental  deflections.  (20 marks)  (iii) Design the reinforcement for the most critical slab (Use N12 bars throughout).  Sketch the reinforcement details for this slab.

Determine the following: (i) Squash load Nuo   (10 marks)  (ii) Nu   and Mu about the major axis for the neutral axis depth (dn) values of do,  0.8do, 0.545do, 0.4do, and 0.2do, where do is the distance from the top concrete  fibre in compression to the centroid of the bottom reinforcement in tension.  (15 marks)  (iii) Use the values obtained in (ii) to develop the beam column interaction (Mu    and Nu) diagram for the column.  (10 marks)  (a) Cross section of the Column  (b) Bending moment acting on the column Figure 2. Beam Column Section    (iv) If the column is braced, has a length, L (Figure 2.b), and is required to carry N*  = 0.50Nuo kN, what is the value of M*2 that could be carried by the column  considering the slenderness effect?  Assume that G/(G+Q) = 0.30.  (10 marks)  (v) Check if the column is adequate to carry N*= 0.50Nuo kN and bending  moments, i.e. M*x=M*y of 0.5Mub in both directions. If the column is  inadequate for bi-axial bending and axial compression, suggest at least 3 ways  on how this issue can be rectified.  (15 marks)  (vi)      Design the lateral reinforcement (ties) for this column.

Determine the following: (i) Maximum initial prestress at transfer that can be applied at the mid span to  satisfy the code requirement (Assume f’cp as 0.80f’c)  (10 marks)  (ii) Minimum effective prestress required at the mid span when the beam is fully  loaded at service.  (10 marks)  (iii) From (i) and (ii), the optimum initial prestress [Pi] that can be applied at the  mid span. Assume total loss as 12%.  (05 marks)  (a) The jacking force at the end of the beam assuming that prestressing is  applied from both end and the friction force between mid span and end is  6%.  (05 marks)  (b) Required number of 12.7 mm diameter 7-wire ordinary strands to  effectively apply the required jacking force.  (05 marks) (iv) Determine the ultimate moment capacity of this beam and identify whether it  satisfies the strength requirement. At the limit state strength condition, the  beam should satisfy the requirement M*  Lx If Ly/Lx  2: one-way slab Two-way slab supported on four sides  (Foster et al., 2010) Methods of Analysis Section 6.10.3, AS3600 specifies the method of structural analysis to  determine the action effects and deformations in a reinforced concrete  structure to comply with the strength and serviceability requirements.
