Desing a trapezoidal footing to support the two $520mm$ X$520$ columns $5\mathrm{.}80$meters apart. Column $1$ carries a dead load of $1500kN$ and a live load of $750kN.$ Column $2$ carries a dead load of $950kN$ and a live load of $650kN.$ Allowable soil pressure $=182\mathrm{.}50$kPa, $f{c}^{\text{'}}=20\mathrm{.}75$kPa,$fy=414\mathrm{.}50$kPa. Assume weight of footing to be $15\%$ of the column load.
