X $=6$ ft

Y $=5$ ft

The linear load on typical center beams is $700$ #$/$ft$.($Instead of point loads from joists, we will consider the load from the floor will act directly as a linear load on the beams.$)$

There are $12$ beams $($spans $1-2$ & $2-3),6$ girders $($spans A$-$B & B$-$C$),$ and $9$ columns.

What is the total load on the girder on grid $2,$ between B and C$?$
