engineering recuitment GATE CE 2023-24 Test Series Reinforced Concrete Structures Prestress Concrete
A post-tensioned PSC member whose prestressing force is 1600 kN with initial stress in the cable being 1580 N/mm2.
Calculate the combined loss due to shrinkage, relaxation of steel, and anchorage slip (in N/mm2, up to two decimal places).
(Take Es = 2 × 105 N/mm2, Ec = 30 × 103 N/mm2, total anchorage slip 3 mm, relaxation of steel 3%, μ = 0.25, k = 0.002/m, Creep coefficient = 1.6, jacking is done from both ends prestressing force is transferred after 28 days).
Enter numerical value using the virtual keypad. Round off where necessary.
