A pre-stressed concrete beam 200 mm wide and 300 mm deep is used over an effective span of 6 m to support an imposed load of (8+24) kN/m3. at mid span section; a) Find the concentric pre-stressing force necessary for zero fiber stress at the soffit of the beam when it is fully loaded. b) Find the eccentric pre-stressing force necessary for the stress to be zero at the bottom if eccentric prestressing force is located at 100mm from the bottom of the beam.
