Question
A rectangular concrete beam 262 mm wide and 388 mm deep is simply supported over a span of 9.76 m. the beam is reinforced with straight tendons situated 56 mm above the bottom of the beam under a prestressing force of 671 kN. The beam is carrying a concentrated load 57 kN at midspan, a live load of 19.5 kN/m³ and a dead load of 23.1 kN/m³ excluding its own weight. Concrete weighs 18.61 kN/m3 with modulus of elasticity Ec-15,679.2 MPa. Assuming tension concrete does not crack. what is the midspan deflection due to the given loads. (Include the sign if it is negative)
