Reinforced Concrete Beams-1 1. The span length and cross section of a reinforced concrete beam are shown. The beam is under reinforced. The concrete and reinforced steel properties are \\( f_{c}^{\\prime}=3000 p s i, f_{y}=40000 p s i \\), and \\( A_{s}=3 i^{2} \\). Neglecting beam self-weight and based only on the allowable moment capacity of the beam as determined using American Concrete Institute (ACI). Determine the maximum allowable live load \\( \\mathrm{P}_{\\mathrm{L}} \\). (A) \\( 23000 \\mathrm{lbf} \\) (B) \\( 29000 \\mathrm{lbf} \\) (C) \\( 35000 \\mathrm{lbf} \\) (D) \\( \\quad 50000 \\mathrm{lbf} \\)
