A Simply supported 10m long beam with cross-section shown supports a uniform live load of 20kN/m, a concentrated live load of 80kN located at 3m from the left support. Consider the weight of concrete of 23.54kN/m. The beam is pre-stressed by means of 15 wires of 5mm diameter located at 75mm from the bottom of the beam and 5 wires of 5mm diameter located at 40mm from the top of the beam. Assuming the pre-stress in the steel is 800MPa, calculate the stresses at the extreme fibers at the location of the maximum moment of the beam. 100 H K 400 140 350 120 A Simply supported 10m long beam with cross-section shown supports a uniform live load of 20kN/m, a concentrated live load of 80kN located at 3m from the left support.
