(a) Refer to the following simply-supported RC beam: Beam Section 12 in by $20\mathrm{in}$ Effective Depth $=1^{?}$s in I one laver of steel, Effective Depth $=1^{?7}$ in (two lavers of st??) Antoun of Botlom Steel $=3.5\mathrm{in}2$ Make a brief discussion on the results taking into account the variation of bond stress with shear force and variation of bond stress with the size of bars. Fill the following table for two scenarios of reinforcing bars (use WSD):
