2. A 300 mm x 400 mm concrete beam has a span of 5.5m. A post tension force of 600 kN was applied at a point 60mm above the bottom of the beam. Assume concrete would not crack in tension. f.=20.7MPA. Unit weight of concrete is 23.5 kN/m3. Compute the following: а. Deflection due to prestressing force of 600 kN. b. Net deflection of the beam immediately after transfer. P P 60mm 5.5m
