Problem $2(20$ pts$)$ Consider the following building, with the floor plan and associated building section shown in $($a$)$ and $($b$),$ respectively. $(1)$ Compute the tributary areas for $($i$)$ floor beam B$1,($ii$)$ girder G$1,$ girder G$2,($iii$)$ corner column C$1,$ and interior column C$2.($Note: Please use the tributary area method taught in class$)(2)$ Assume a live load of $60$ lb$/$ft$2$ on all three floors. Calculate the axial forces produced by the live load in column C$2$ in the third and first stories. $($Note: you do not need to do live load reduction as in the textbook$).$
