Question Plot moment-curvature relationship for the prestressed concrete section. Use Fsc and Aps from the given table below. Evaluate M and for each of the following load stages: 1. Initial stage under zero applied moment. 2. At zero curvature. 3. At cracking. 4. Beyond cracking, when the top fiber strain is 0.001. 5. At ultimate, when the top fiber strain is 0.003. punigung A f.
