PART B 16marks (CE6702 Prestressed Concrete Structures Question Bank)
1. A rectangular concrete beam 100mm wide & 250mm deep spanning over 8m is prestressed by a straight cable carrying a effective prestressing force of 250kN located at an eccentricity of 40mm. The beam supports a live load of 1.2 kN/m.
a) Calculate the resultant stress distribution for the centre of the span cross section of the beam assuming the density of concrete as 24kN/m2 (CE6702 Prestressed Concrete Structures Question Bank)
b) Find the magnitude of prestressing force with an eccentricity of 40mm which can balance the stresses due to dead load & live load at the soffit of the centre span section
2. A PSC beam of 120mm wide and 300mm deep is used over an span of 6m to support a udl of 4kN/m including its self weight. The beam is prestressed by a straight cable carrying a force of 180kN & located at an eccentricity of 50mm. Determine the location
of the thrust line in beam & plot its position at quarter & central span sections.
