The layout of a 200 mm thick unrestrained slab over a proposed single garage has internal dimensions of 6000 x 3000 mm and supports a live load of 1.5 kN/m². It is supported by 230 mm thick walls. The environmental conditions are mild, and 1 hr fire rating is required. Determine the suitable reinforcement and check the code requirements for shear, minimum area of reinforcement and bar spacing. Assume deflection is ok (no need to check), fcu= 30 MPa, fy = 450 MPa and Ø 12 mm reinforcement bars for effective depth.
