Extracted text: A 250mm x 600mm 10m-simple span prestressed concrete beam has a uniformly distributed dead load of 8.50 kN/m in addition to its weight. The tendons are placed 100mm from the bottom of the beam and is subjected to initial prestress force of 1880 kN. The beam is used to carry a live load of 25 kN/m. If the unit weight of concrete is 24 kN/m3, determine the stress at the bottom fiber of the beam at midpan after 20% of the losses at its final stage CS Scanned with CamScanner
