A two-way slab with 150 mm thickness, supported by T-beams and L-beams is proposed for a resident building shown in Figure 2. The beams that support the four sides of each slab panel are all bw 300 mm thick. Reinforcement is to be N12 bars. The characteristic concrete. compressive strength is to be fe= 32 MPa. Assume that the density of reinforced concrete in the slab is 24 kN/m³. The superimposed nominal loads are: Dead load g = 1.0 kPa (self-weight excluded) and Live load q = 4 kPa. (a) For serviceability, considering total deflection only, is this slab adequate in accordance with the "Deemed to comply" requirements of CL 9.3.4.1 and CL 9.3.4.2? Notwithstanding your answer to Part (a), please continue to use a slab thickness of D, = 150 mm for Parts (b). (b) Considering the minimum reinforcement requirements of CL 9.1.1 b for strength and of CL 9.4.3 for shrinkage and temperature effects, what is the minimum reinforcement required in each direction of slab panels 1 to 4. (Minor degree of crack control) (c) Please show the sketches regarding the arrangement of the reinforcement for slab panels 1 to 4. 5000 S1 S3 Figure 2 8000 S2 S4 I 6500 4500 A two-way slab with 150 mm thickness, supported by T-beams and L-beams is proposed for a resident building shown in Figure 2.
