A simply supported beam is post-tensioned by a straight tendon with an initial prestressing force of 2000 kN as shown in Figure 3. The beam will support a uniform service live load (SL) of 20 kN/m and a concentrated live load of 5 kN as shown. Determine the extreme concrete fiber stress (top and bottom) at a point 5 meters from the left support Situational Problem 14: under the initial condition (at transfer), when the initial prestressing force and weight of the beam is acting, using superposition, kPa; Situational Problem 15: under the final condition, after a prestress loss of 10% in the initial prestressing force due to anchoring and upon the application of the service live loads, using the internal-couple
