A pretensioning concrete beam of rectangular concrete cross-section, 150 mm wide and 300 mm deep, is pre-stressed by eight high tensile wires of 7 mm diameter located at 100 mm from the soffit of beam. If the wires are tensioned to a stress of 1100 N/mm2, calculate the percentage loss of stress due to elastic deformation assuming the modulus of elasticity of concrete and steel are 31.5 and 210 kN/mm2.Long Answer 5 Marks May-2020 • PSBTE DIPLOMA

A rectangular concrete beam of cross-section 30 cm deep and 20 cm wide is prestressed by mean of 15 wires of 5 mm diameter located 6.5 cm from the bottom of beam and 3 wires of diameter 5 mm located at 2.5 cm from the top. Assuming the prestress in the steel as 840 N/mm2, calculate the stresses at the extreme fibers of mid span section when the beam is supporting its own weight over a span of 6 m. If a uniformly distributed live load of 6 kN/m is imposed, evaluate the maximum working stress in concrete. The density of concrete is 24 kN/m3.Long Answer 10 Marks May-2020 • PSBTE DIPLOMA
