The framing plan represents a typical floor in a low$-$rise office building. The floor decking spans in a direction from line $1$ toward line $4$ Assume all beam members are simply supported.

Roof dead load: $45psf$

Roof snow load: $25$ psf

Floor occupancy live load: $80$ psf

Interior floor dead load: $70$ psf$.$

There are no cantilever slabs.

Determine the maximum axial gravity load on column B$2$ at the ground floor which supports three levels of interior floors plus the roof. Incorporate live load reduction. Use the ASCE $7-16$ LRFD load combinations and live load reduction equation found in the FE Reference Handbook.
