Question: Problem 4 : ( 3 0 points ) A continuous beam has a typical span of 3 0 f t . the beam is 3

Problem 4: (30 points)
A continuous beam has a typical span of 30ft. the beam is 30 in deep and reinforced with 2#9 top bars. The inflection point is located at 3ft measured from the support.
Determine the length required for the top bars to resist the moment.
Assume that the bar is epoxy coated and the effective depth, d=27in.F'C=4ksi and Fy=60ksi.
