A partial floor plan is shown in the figure.

The specified loads are as follows:

Dead load of $4\mathrm{.}5$kPa, including floor weight and permanent fixtures.

Occupancy Live Load of $4\mathrm{.}8$kPa, with a corresponding live load reduction factor of $1\mathrm{.}0.$

Girder G$1$ and beam B$1$ are laterally supported. Assume the self$-$weight of the beam and girder are neglected. Use G$40\mathrm{.}21345W$ steel. Determine the load affects of girder G$1($W$530$x$123)$ based on ULS & SLS design requirements. Consider the load case $1\mathrm{.}25$D$+1\mathrm{.}5$L as the governing load case.
