Q-A pre-tensioned concrete member of section 200 mm x 250 mm contains tendons of area 500 mm² at centre of gravity of the section. The prestress in the tendons is 1000 N/mm². Assuming modular ratio as 10, find the stress (N/mm2) in concrete.
Use f'c = 30 MPa and fy = 415 MPa. The unit weight of concrete is 24 kN/m³ . The floor of a cantilever floor system is made up of a 150mm thick concrete slab (cast monolithically with beam) and the beams have widths of 300 mm, a total depth of 560 mm, and are to be reinforced with 5-Ø28 mm bars. The center-to-center spacing of beams is 4 m. The cantilever floor system is also built using 4m cantilever reinforced beams as supports. a) Find the maximum service live load (kPa) that the current floor design can support. b) Suppose that the floor will need to carry a superimposed service dead load of 2 kPa and service live load of 7.2 kPa, will the existing floor design be adequate? If not, redesign the beams (find the appropriate number of Ø28-mm rebars and provide a final sketch). Use cc = 40 mm, stirrup diameter of 10 mm, and nominal maximum aggregate size of 20 mm.
