engineering recuitment GATE CE 2023-24 Test Series Reinforced Concrete Structures Prestress Concrete Analysis of Prestress
A post tensioned concrete beam, 200 m wide and 450 mm deep is prestressed by a circular cable (total area = 800 mm2), with zero eccentricity at the ends and 150 mm at the centre.The span of the beam is 10 m. The cable to be stressed from one end such that an initial stress of 840 N/mm2 is available in the unjacked end immediately after anchoring. Determine the stress (in N/mm2) in the wires at the jacking end. ( μ=0.6,k=0.003/m)
