Problem # $2$:

Check the moment strength at the base of the structural RC wall shown below. The given lateral loads are strength$-$level wind forces, considering both direct lateral forces and the effects of any torsion. Use a load factor of $1\mathrm{.}0$ for the wind load effects. The given vertical loads represent dead loads, and you can assume that the vertical live loads are equal to $60$ percent of the dead loads. Assume the wall is constructed with normal$-$weight concrete that has a compressive strength of $28$MPa. Assume all of the steel is Grade$-60$ with $f_y=420$MPa.
