600 Figure 2 shows the effective cross-section of a reinforced concrete T-beam. The following data 100 apply: o O Asc Concrete: fc' = = 32 MPa, Ec = 28,600 MPa 300 1000 4800 mm, Bottom reinforcement: Ast fsy = 500 MPa, Es = 200,000 MPa Ast = 1400 mm2, ZUR Top reinforcement: Asc fsy = 250 MPa, Es = 200,000 MPa Figure - 2 At a particular value of bending moment in the service load range, with all materials behaving elastically, the depth to the neutral axis is 300 mm and the tensile strain in the bottom reinforcement is 0.00113. Working from first principles: a) Check that the value given for the neutral axis depth is correct; b) Calculate the magnitude of the bending moment.
