Question
Transcribed Image Text:A prestressed concrete beam with a cross section 300 mm width and 600 mm depth, is 12 m long.
It carries a live load of 12 kN/m in addition to its self weight. It is prestressed with 2000 mm² high
tensile steel located at 175 mm from soffit. The cable profile is straight for full length of the beam
and it is stressed to a level of 800 N/mm². It is bonded to concrete. Determine the location of thrust
line in the beam and plot its position at end, and at mid span section.
Assume
Es = 6.0
