2.2 A simply supported reinforced concrete beam has an effective span of \( 8 \mathrm{~m} \) and crosssection dimensions as shown in Fig.1. The imposed loading is \( 20 \mathrm{kN} / \mathrm{m} \) and the dead load (inclusive of self-weight) is \( 16 \mathrm{kN} / \mathrm{m} \). Design the beam reinforcement for Ultimate Limit State for bending and shear given: \( f_{\mathrm{cu}}=30 \mathrm{~N} / \mathrm{mm}^{2}, \mathrm{f}_{\mathrm{y}}=500 \mathrm{~N} / \mathrm{mm}^{2} \) and \( \mathrm{f}_{\mathrm{yv}}=250 \mathrm{~N} / \mathrm{mm}^{2} \) Produce sketches of the beam showing loading and the final designed cross-section.
