The superimposed live load is $40$ psf$,$ the superimposed dead load is $15$ psf and the slab has a self$-$weight of $80$ psf$.$ Size of the beams are shown in the figure. Assume all connections are simple connections unless otherwise specified $($e$.$g$.$ transfers shear but not moment$).$ Do not consider live load reduction

$-$ Calculate the live and dead loads acting on Beam B$,3-4.$ Present your answers on free body diagrams $($one for dead load, one for live load$)$ and include end forces.

$-$ For the Beam B$,3-4,$ use the max live and dead load shear and moment values to calculate the required shear strength $($Vu$)$ and moment strength $($Mu$)$ for the LRFD load combinations.
