For the same building in Problem $1,$ considering live load for typical residential buildings, compute the

following:

a$)$ The distributed live load on girder G$1.$

b$)$ The distributed live load on joist J$1.$

c$)$ The axial force of the first story column C$1$ due to live load $($roof live load is not the same as floor live load;

consider standard roof live load on a roof with a slope of $1\mathrm{.}5$in$./$ft$).$
