A prestressed concrete rectangular beam has area of cross-seciton equa

1.	A prestressed concrete rectangular beam has area of cross-seciton equal to 36000mm2 and moment of inertia of 2.7×108mm4. A prestressing force of 195 kN is applied by tendons at an eccentricity of 55 mm from neutral axis.The loss of stress in steel due to creep of concrete is ____ N/mm2.[Take Es=2×105N/mm2,EC=3×105 N/mm2 and creep coefficient = 1.50]76
Answer» A prestressed concrete rectangular beam has area of cross-seciton equal to $36000 m m^{2}$ and moment of inertia of $2.7 \times 10^{8} m m^{4}$ . A prestressing force of 195 kN is applied by tendons at an eccentricity of 55 mm from neutral axis. The loss of stress in steel due to creep of concrete is ____ $N / m m^{2}$ . [Take $E_{s} = 2 \times 10^{5} N / m m^{2}, E_{C} = 3 \times 10^{5} N / m m^{2}$ and creep coefficient = 1.50] 76
