The prestress T-beam section has a simple span of 6 m. The tendons is subjected to an initial stress of 900 MPa with an area of 800 mm2. Assuming a loss of stress of 18%, no tension will be acting at the bottom and a maximum stress of 9.5 MPa at the top should not exceeded. -450 100 800 100 -150- Determine the safe moment that the beam could carry based on the allowable stresses. (kN-m)
