A pretensioned prestressed concrete beam having a rectangular section with a width of 150 mm and overall depth of 350 mm is prestressed by tendons of effective area 461 mm² at an effective depth of 300 mm. Assuming the characteristic strength of concrete and steel as 40 and 1600 N/mm², estimate the ultimate flexural strength of the section using the provisions of the Indian Standard Code. Use Ultimate stress in tendon fᵤb = 1253 N/mm²and Neutral axis depth xᵤ = 234.9 mm.
