A simply supported post tensioned beam has a parabolic cable with zero eccentricity at both ends. The span of the beam is L= 20m. Calculate the friction losses and anchorage set losses through the beam. The duct is bright and zinc coated metal. The beam is jacked from the left-end only. Data: fc=32Mpa, Strand diameter=21.7 mm, Draw in wedges=6mm, duct diameter=110 mm, Ap= 4000mm2, Ep=195000Mpa, 31 strands , Pj =5832 kN, Betap=0.0104, miu=0.2. The eccentricity at the mid span is 400mm. Calculate part 1 friction losses
