A prestressed concrete beam having a cross-sectional area (A) of >X IUmm is simply supported over a span of 10 m. It supports a uniformly distrib- uted imposed load of 3 kN/m, half of which is non-permanent. The tendon follows a trapezoidal profile with an eccentricity of 100 mm within the middle-third of the span and varies linearly from the third-span points to zero at the supports. The area of tendons Ap = 350 mm² have effective prestress of 1290 N/mm² immediately after transfer. Using the following data, calculate 1. the short-term deflections, and 2. the long-term deflections. Assume = 4.5 × 108 mm* E = 34 kN/mm2² A = 5 x 10¹ mm² = 200 kN/mm² E₂ Density of concrete = 23.6 kN/m³ Creep coefficient = 2 Concrete shrinkage, & = 450 x 10-6 Relaxation of steel stress = 10%
