A pretensioned member with a dimension of 250mm x 360mm is subject to an eccentric
tendon that is located 105mm from the soffit. Area of the prestressing steel to be 502 sq.
mm and the modulus of elasticity is 200 GPa. The Modulus of elasticity of concrete is 36.8
GPa. Creep coefficient = 1.6 and the shrinkage strain = 3 x10^6. Assume a 5% steel
relaxation. Find the total prestressed loss in percentage.
