An hollow box beam spans \( 30 \mathrm{ft} \). The cross section of the beam is shown below. Use \( f_{c}=5,500 \mathrm{psi} \) and \( f_{y}=60,000 \mathrm{psi} \). The ultimate loads are shown, i.e., do not factor the given loads. With proper calculations, evaluate whether the beam has adequate flexural capacity. For simplicity, ignore the compression bars. \( P=3 \cap \mathrm{k} \)
