4) A precast T beam with the dimensions shown below is to be a used as a bridge over a small roadway. The beam is used on a 30 ft simple span, and the total factored load including the beam's self-weight is 15.6 kips/ft. Assume d = 21" for your calculations. fc' = 6000 psi and fy = 60000 psi. a. Calculate the maximum mid-span moment - this is Mu b. Check the effective width of the beam as per ACI 318-19 Table 6.3.2.1 C. Check whether the T-Beam designed as a rectangular section would be able to provide the required Mu. If not, design the section as a T-Beam to calculate the required reinforcement. Try to keep close to 0.9 (it is okay if it's a little under). But calculate the correct value of .
