Question
Consider the prestressed concrete beam shown below, which is to be used in an industrial
building construction. The beam is only reinforced with prestressing steel and no mild
reinforcement is used. What is the maximum live load that this beam can carry (in addition to
the self weight) considering only the allowable section stresses at Midspan? Blank 1
The material properties and prestressing are as follow:
300mm
600тm
15 m
fe= 40MPA
fpu = 1860 MPa
Afpr = 140MPA (total losses) Aps = 84,13 = 8 x 99mm²/strand
fa= 35MPA
fpi= 1120MPA
70mm
300тт
f, = 0.5f, and f, = 0.45f,
