Question

A prestressed concrete beam is simply supported over a span of 11 m. the beam is reinforced with straight tendons situated as shown in the figure under a prestressing force of 682 kN. The beam is carrying a live load of 16.14 kN/m² and a dead load of 22.09 kN/m² excluding its own weight, Concrete weighs 20.39 kN/m³ with modulus of elasticity Ec=17,459.32 MPa. Assuming tension concrete does not crack, what is the midspan deflection due to the given loads. (Include the sign if it is negative)
