A square footing $1\mathrm{.}8$mX$1\mathrm{.}8$m is loaded with an axial load of $1800$ kN and Mx $=450$kNm and My

$=360$kNm$,$Given $=36$o

$,$ depth of footing $=1\mathrm{.}8$m$,=18$kN$/$m$3$ WT at $6$m below GL$,$ determine net

ultimate bearing capacity and factor of safety against shear failure. For $=36$o take Nq$=38$ and

N$=56.$Use IS$6403$ recommendations and useful width concept....... get soultion within $15$ minutes
