Question

The cross section of the simply supported pre-tensioned concrete beam has a width of 300mm and a total depth of 500mm. The beam has straight cables with initial prestress force of 964kN and a final prestress force of 624kN after five years. The concrete is uncracked, with a modulus of elasticity of 27 646 MPa. The cables are placed 400mm below the top most fiber of the beam. The superimposed dead load and live load are 12kN/m and 8kN/m respectively. Assume concrete weights 23.5kN/m^3. Spab of beam=9m. A. Determine the deflection immediately after the cable are cut. B. Determine the deflection after 5 years.

Example 2. The cross section of the simply supported pre-
tensioned concrete beam has a width of 300 mm and a
total depth of 500 mm. The beam has straight cables with
initial prestress force of 964 kN and a final prestress force
of 624 kN after 5 years. The concrete is uncracked, with a
modulus of elasticity of 27 646 MPa. The cables are placed
400 mm below the top most fiber of the beam. The
superimposed dead load and live load are 12 kN/m and 8
kN/m respectively. Assume concrete weights 23.5 kN/m^3.
Span of beam = 9m.
a. Determine the deflection immediately after the
cables are cut.
b. Determine the deflection after 5 years
