A rectаngulаr beаm with crоss sectiоn b = 14 in., h = 24 in., and d = 21.5 in. suppоrts a total factored uniform load of 2.20 kips/ft, including its own dead load. The beam is simply supported with a 23-ft span. It is reinforced with four No. 7 Grade 60 bars, two of which are cutoff between midspan and the support and two of which extend 10 in. past the centers of the supports. The concrete strength is 6,000 psi (normal weight). The beam has Grade 60 No. 3 stirrups satisfying ACI 318-14 Sections 9.7.6.2.2 and 9.6.3.3. The strength of the four bars is φMn = 221.3 kip-ft, and the strength of the remaining two bars is φMn = 113.4 kip-ft. Determine the distance from the support to the theoretical cutoff point (i.e. disregard ACI 318-14 Section 9.7.3.3).
