Extracted text: For the following problem sections, please consider the figure below: Given that the flexural design moment is 301 ft-k, assume that this moment is caused as a result of a uniformly distributed load that results from the self-weight of the beam and a live load to be calculated. The span of the cantilevered beam is 15-ft. Assume #4 stirrups are used as shear reinforcement and specify the spacing of the stirrups for the three shear reinforcement zones, as applicable. Assume fy = 60,000 psi and f, = 4,000 psi. (20 pts.) а) Using the deflection equation below, a deflection equation for a uniformly distributed load on a cantilever beam, calculate the initial deflection of the self- weight of the beam and the live load as calculated in part a). (20 pts.) b) c) If 20% of the live load is more or less sustained, calculate the long-term deflection of the sustained loads after five (5) years.
